MECHANICAL HAZARDS

DO NOT operate the machine unless all protective guards are in place. 
KEEP handles and feet clear of rotating and moving parts as they will cause injury if contacted. 

ENSURE that the motor operation switch is in the OFF position and the spark plug ignition lead is 
disconnected befare removing the guards or making adjustments. 
ENSURE both the machine and the operator are stable by setting up on level terrain and the machine 
will not tip over, slide of fall while in operation or unattended. 
DO NOT leave the machine in operation while it is unattended. 
ENSURE that the walls of a trench are stable and will not collapse due to the action of the vibration, 
prior to commencing compaction. 
ENSURE that the area to be compacted does not contain any "live" electrical cables, gas, water or 
communication services which may be damaged by the action of vibration. 
EXERCISE CARE when operating unit. Exposure to vibration or repetitive work actions may be harmful 
to hands and arms. 
NEVER stand on the unit while it is operating. 
DO NOT increase the governed no-load motor speed above 3,500 r/min. Any increase may result in 
personal injury and damage to the machine. 
BE CAREFUL not to come in contact with the muffler when the engine is hot, since it can cause severe 
burns. ENSURE that the repairs to the motor and machine are carried out by COMPETENT personnel.

FIRE & EXPLOSION HAZARDS

EXCESSIVE NOISE can lead to temporary or permanent loss of hearing. 
WEAR an approved hearing protection device to limit noise exposure. As required by Occupational 
Health and Safety regulations. 

PROTECTIVE CLOTHING 

ALWAYS wear approved hearing protection when working in a confined work space. Protective gog-
gles and a dust mask should be worn when working in a dusty environment. Protective clothing and 
footwear may also be desirable when working with hot mix bitumen. 

ADDITIONAL HAZARDS

Slip/Trip/Fall is a major cause of serious injury or death. Beware of uneven or slippery work surfaces. 
Exercise care when working in the vicinity of unprotected holes or excavations. 

6. OPERATION 

Pre-start-up inspection 
The following Pre-start-up inspection must be performed before the start of each work session or 
after every four hours of use, whichever is first.. lf any fault is discovered, the compactor must not be 
used until the fault is rectified. 
Thoroughly inspect the compactor for signs of damage. Check components are present and secure. 

Pay special attention to the belt drive safety guard fitted between the engine and the vibrator unit. 
2. Check the engine oil level and top up as necessary.
3. Check the engine fuel level and top up as necessary.
4. Check for fuel and oil leaks

Start and stop Procedure 

Diesel Engine 

1. Open the fuel cock.
2. Turn the governor lever to "STARTING" position.
3. Hold the recoil starter handle.
4. Pull the starter handle until you feel the resistance, then return handle slowly. 
5. Press the decompression lever to "Non-compression" position. The lever will return back automa-
tically after the engine started.
6. Hold the recoil starter handle with two hands and pull it hardly.
7. lt is difficult to start the engine at cold weather. Remove the rubber plug on the cylinder head and 
fill about 2CC engine oil before starting.
8. To stop the engine, set the governor lever to the low speed position, then run the engine at zero 
load five minutes.
9. Set the governor lever to the "STOP" position. Do not stop the engine with the decompression lever.
10. Set the fuel cock the "OFF" position.
11. Pull the recoil starter handles slowly, until you feel resistance. (At this point, the decompression 
just begins and intake/exhaust valves are both closed, thus the cylinder can be prevented from rust.)

Petrol Engine 

1. Open the fuel tap by moving the fuel ON/OFF lever fully to the right.
2. lf starting the engine from cold, set the choke ON by moving the choke lever fully to the left. lf 
restarting a warm engine, the choke is usually not required. However, if the engine has cooled to a 
degree, partial choke may be required.
3. Turn the engine ON/OFF switch clockwise to the "1" position.
4. Set the throttle to the idle position by moving the throttle lever fully to the right. Do not start the 
engine on full throttle, as the compactor will vibrate as soon as the engine starts.
5. Taking a firm hold of the control handle with one hand, grasp the recoil starter
6. handle with the other. Pull the recoil starter until engine resistance is felt, then
7. let starter return.
8. Taking care not to pull the starter's cope fully out, pull the starter handle briskly.
9. Repeat until the engine fires.
10. Once the engine fires gradually, set the choke lever to the OFF position by 
11. moving it to the right.
12. lf the engine fails to fire after several attempts, follow the trouble-shooting guide on page 9.
13. To stop the engine, set the throttle to idle and turn the engine ON /OFF switch anticlockwise to 
the "O" position.
14. Turn the fuel off.
The machine is best suited to the compaction of bituminous and granular materials e.g. granular soils 
such as silt and clay are best compacted using the impact force produced by a vibrating rammer. 
Where possible the site should be graded and leveled before commencing compaction. 
Correct moisture content in soil is vital to proper compaction. Water acts as a lubricant to help slide 
soil particles together. Too little moisture means inadequate compaction; too much moisture leaves 
water-filled voids that weaken the soil's load-bearing ability. 
Compaction of dry materials will be facilitated by moistening with a water hose fitted with a sprinkler. 
Excessive watering or water content will cause the machine to stall. 
The optional water tank kit is recommended when the machine is used on bituminous surfaces as 
the water film prevents a build up of material on the underside of the plate. 
Use unleaded grade petrol and ensure that the fuel is free from contamination. 
The vibratory motion provides a self propelling action. Position the handle at the opposite end of the 
machine to the vibrator. 
For more information on starting and correct operating procedures of the motor, refer to the motor 
operation manual supplied with the unit. 
lncrease the motor speed to the maximum setting using the hand throttle lever, before commencing 
compacting. 
The machine should be controlled by grasping the handle with both hands and applying restraint to 
control the forward motion. 
Steer the machine by moving the handle sideways to the right or left. 
ALWAYS maintain good footing so that you do not slip and loose control when starting or operating 
the machine. 
lf the optional water tank is fitted, the flow rate can be controlled by adjusting the cock in the supply 
hose to sprinkler bar. 
lnspect the water hose and its connections to ensure that they do not leak. 

7. CARE AND PREVENTIVE MAINTENANCE 

Check the oil level in the motor crankcase daily. 
lnspect the rubber anti vibration mounts for wear or deterioration. 
lf the optional water tank is fitted inspect the water hose and its connections to ensure that they do 
not leak. 

Clean the underside of the plate regularly to prevent a build up of material.

These inspection intervals are for operation under normal conditions. Adjust your inspection inter-
vals based on the number hours plate compactar is in use, and particular working conditions. 

DAILY SERVICE 

• Check for leakage of fuel or oil.
• Remove soil and clean the bottom of compaction plate.
• Check engine oil.
• Check for loose screws including tightness. See Table 3 above (tightening torque), for retightening.

CHANGING VIBRATOR OIL / VIBRATOR GREASE 

When changing the vibrator oil, remove the drain plug located at the bottom-right of the vibrator, and 
simply tip the compactar to drain the oil. Note that the oil will drain more easily while it is hot. Far 
FPC50 series, FPC60 series,FPC80 series,FPC90 series, replace the oil with 200ML of 10W-30 motor 
oil; ForFPC100 series, check and regrease exciter every 500 hours of operation, use SHELL ALVANIA 
R3 grease or equivalent. 

AIR FILTER 

1. The air filter element should be cleaned because a clogged air cleaner can cause poor engine 
starting, lack of power and shorten engine life substantially.
2. To clean or replace air filter loasen the wing nut on the air filter housing (Figure 1 ), remove the cover 
and take out air filter cartridge. lf only cleaning of the air filter is desired blow through the air filter 
cartridge from the inside, moving a jet of dry compressed air up and down until all dust is removed.

CAUTION:  NEVER attempt to check the V-belt with the engine running. Severe injury can occur if your 
hand gets caught between the V-belt and the clutch. Always use safety gloves.
Checking and Replacing the V-belt and Clutch
After 200 hours of operation, remove the upper belt cover to check the V-belt tension (Figure 2). 
Tension is proper if the belt bends about 10mm when depressed strongly with finger between shafts. 
Loase or worn V-belts reduces power transmission efficiency, causing weak compaction and reduces 
the life of the belt itself. 
CAUTION:  Whenever the compactoc's v;brat;on becomes weak oc los! dudng oocmal operation 
cegacdless of operation hours, check the V-belt and clutch immediately. 

REPLACING THE V-BELT

Remove the upper and lower belt covers. Engage an offset wrench (13mm) or the like to vibrator pulley 
(lower) fastening bolt. Engage waste cloth or the like at midway of V-belt on the left side and while 
pulling it back strongly, rotate the offset wrench clockwise so that the V-belt will come off. 

REINSTALLING THE V-BELT

Engage V-belt to lower vibrator pulley and push the V-belt to left side of upper clutch and, in the same 
manner as in removal, rotate offset wrench clockwise so that the V-belt goes back on. 

CHECKING CLUTCH

Check the clutch simultaneously with V-belt checking. With belt removed, check outer drum of the 
clutch far seizure and "V" groove far wear or damage with your eyes. Clean the "V" groove as neces-
sary. Wear of lining or shoe should be checked with running check. lf the shoe is worn, power trans-
mission becomes deficient and slipping will result.
