are described in
Pic. 4
. All of the four described main positions
are locked by a simple crimp-lug in the lever body.
1.
Check the oil level; if necessary, fill the engine with the recommended type and amount of oil. Fill the tank with the recommended
type and amount of gasoline.
2.
Move the throttle lever into the
4
CHOKE
position.
3.
Pull the manual starter rope to start the engine
4.
Leave a new or cold engine to run for approx. 30 second with choke
4
CHOKE
position), then move the
throttle lever to the
3
MAX
position. Let the engine run in this position for approximately 30 seconds.
Do not leave the machine unattended!
Both of the control levers (
1
and
2
in
Pic. 3) must be in the off position (must not be depressed to the
handles)!
2.4.2.1 Activating the work tool
Before every use, check that the screws that fasten the work tool and those of the protection elements, covers,
and engine are properly tightened!
Ensure that all persons, children, and pets are located at a SAFE distance from the machine! If not, do not
continue in further activity!
1.
Start the engine
. Set the maximum engine RPMs using the throttle lever. If the engine is cold, let it warm up for about 1 minute
at maximum rpm.
2.
Grasp the left handlebar with your left hand. Use your right hand to move (lift) the
right control lever
(
1
on
Pic. 3
) into upper
position until it is fully inserted into the
calliper with cables
(
17
on
Pic. 3
).
3.
Push the
safety button
(
16
on
Pic. 3
) on the calliper with cables in the direction of the arrow.
4.
Using a slow and smooth motion, press the control lever on the right handle using your right hand. Hold the button until the
control lever begins moving with the calliper.
Press the lever slowly and steadily so that the work tool manages to engage without stalling the engine.
The levers on the handlebars can be easily moved and the force required to hold the handles in operating position is
minimal when compared to regular machines available on the market.
5.
After the work tool has begun spinning, depress the lever fully and firmly hold it along with the handle.
Always fully depress the clutch lever to the handles. Failure to depress the clutch lever fully will cause damage to
the V-belt.
6.
Engagement of the work tool is accompanied by partial slipping of the V-belt and associated side effects (chattering, squealing).
After the belt is worked in, this phenomenon usually disappears.
A new or cold engine may occasionally stall when engaging the work tool drive the first few times. This will disappear
after the engine has warmed up.
If the work tool drive cannot be engaged after the engine has warmed, check to see if any of the defects listed in
Table 8 are present.
2.4.2.2 Starting, running the machine
Use the wheel drive clutch lever (
2
on
Pic. 3
) on the left handle to engage the wheel drive. Depress the lever fully to the handle and
the machine will immediately then begin moving forward. The walking speed must match the speed of the machine when depressing the
lever and starting the machine!
The drive clutch is engaged by a V-belt, you can depress the clutch slowly – the machine will gradually move forward
without jerking.
Always fully depress the wheel drive clutch lever to the handles. Failure to depress the clutch lever fully will
cause damage to the V-belt.
The wheel drive clutch lever cannot be used to regulate the drive speed! This will damage the V-belt.
Never move in reverse with the wheel drive clutch lever depressed! Do not overburden yourself with the machine.
2.4.2.3 Stopping the machine
If you need to stop the wheel drive, release the lever on the left handle. The machine wheel drive will stop, but the work tool will still
rotate. The work tool drive is turned off by releasing the lever on the right handle. The automatic brake will stop the work tool. Switch the
throttle lever to the
2
MIN
or
1
STOP
position according to
Pic. 4
62
Switch the lever to the
MAX
position in engines equipped with automatic choke.
63
Directions for starting the engine are described in detail in the engine operating instructions.
64
Engines equipped with automatic choke and throttle lever in MAX position, automatic setting of maximum rpms occurs after the engine has warmed.
