MAINTENANCE
Importance of maintenance
Good maintenance is cost-saving and essential for
safe and trouble-free operation.
WARNING:
Improper maintenance or failure to comply with
instructions, precautions can result in serious injury or
death. Always follow the manual prescribed
procedures and precautions.
To ensure a proper upkeep of your machine, the
following pages include a maintenance schedule and
description plus an inspection procedure of your
machine. For tasks that are more difficult, or require
special tools, maintenance should be carried out by
technician or qualified mechanic.
Maintenance safety
As with any type of power equipment, carelessness or
error on the part of the operator can result in serious
injury. It is impossible to warn against all hazards or
hazardous situations, it is therefore important that the
user of the machine exhibits vigilance to operate the
machine safely and rationally to avoid bringing yourself
and others in danger.
Safety precautions
Important:
Before commencing any maintenance or
repair ensure that the engine is shutdown
To reduce the possibility of fire or explosion, be careful
when working around gasoline. Use only a
nonflammable solvent, not gasoline, to clean parts.
Keep cigarettes, sparks and flames and other sources
of ignition away from the machine.
Refueling
With the engine stopped, remove the fuel tank cap and
check the fuel level. Refill the tank if the fuel level is
low.
Fuel recommendations
Use only unleaded gasoline octane 95 or
higher.
Never use stale or contaminated gasoline or
an oil/gasoline mixture.
Avoid getting dirt or water in the fuel tank.
Refuel in a well-ventilated area before starting the
engine. If the engine has been running, allow it to cool.
Refuel carefully to avoid spilling fuel. Do not fill above
the fuel strainer shoulder. After refueling, tighten the
fuel tank cap securely.
Engine oil level check
In order to check the engine oil level correctly the
engine must be stopped and the machine in a level
position.
How to:
Remove the filler cap/dipstick and wipe it
clean.
Insert and remove the dipstick into the filler
neck to check oil level. Note: The Oil level
must be within the specified interval at the end
of the stick. If the oil level is at the lower end of
the interval, refill with oil SAE.
Screw in the filler cap / dipstick securely.
Warning:
Never refill oil over the higher end of the
interval, this will damage the engine.
Engine oil change
Drain the old / staled oil while the engine is warm.
Warm oil is more fluid then cold and drains better.
How to:
Place a suitable container below the engine to
catch the used oil.
Remove the filler cap and the drain plug.
Drain completely!
Reattach the drain plug, and tighten it
securely.
Refill new recommended oil.
Please dispose the used engine oil environmentally
correct. We suggest that you keep the used oil in a
sealed container and dispose at your recycling center
or service station for reclamation. Do not throw it in the
waste; pour it on the ground; or down a drain.
Engine oil specifications
Oil is affecting the performance of your machine and
service life. Use 4-stroke automotive detergent oil. The
SA oil viscosity and service classification are in the API
label on the oil container. We recommend that you use
API SERVICE Category SE or SF oil.
Spark Plug
Check the spark plug for dirt and grime; if necessary
clean it with a copper wire brush.
First time after approximately 10 hours of
operation
Hereafter service the spark plug after every 50
hours of operation.
How to:
Disconnect the spark plug cap, and remove
any dirt from around the spark plug area.
Remove the spark plug with a spark plug
wrench. Inspect the spark plug.
Replace it if the electrodes are worn, or if the
insulator is cracked or chipped.
Measure the spark plug electrode gap with a
suitable gauge.
The gap should be 0.70 - 0.80 m. Correct the
gap, if necessary, by carefully bending the side
electrode.
Mount the spark plug carefully, by hand, to
avoid cross-threading.
After the spark plug seats, tighten with a spark
plug wrench to compress the water. If
reattaching a used spark plug, tighten 1/8 - 1/4
turn after the spark plug seats. If installing a
new spark plug, tighten 1/2 turn after the spark
plug seats.
Attach the spark plug cap.
Notice:
An incorrect spark plug can cause engine
damage.
