2.4.2.2 Putting the machine in motion
To put the machine in motion use lever (2 in
Pict.2
) on the left handle. Press the lever all the way to the handle, and the machine moves ahead
immediately. Adjust the speed of your walk to machine speed as soon as you press the lever and the machine moves.
The wheel drive has a belt clutch; you can press the lever slowly and the machine starts off fluently, not with a jump.
Always press the clutch lever all the way down to the handlebars. If the lever is not pressed properly, it causes damage to the V-
belt.
The wheel drive clutch lever does not adjust travelling speed!
Never reverse with the wheel drive clutch pressed!
2.4.2.3 Machine stopping
If you wish to stop the machine, release the left handlebar lever. The machine stops moving, but the cutting disk spins. The cutting disc drive is turned
off by releasing the right handlebar lever. The cutting disc is stopped by an automatic brake. Shift the accelerator lever into '
MIN
’ or ‘
STOP
’ position.
Always switch off the engine and wait for the cutting disk to stop before starting any activity near the machine! Always switch the
engine off before leaving the machine!
Never leave the engine running at the maximum engine speed for a long time or running idle while the clutch of the cutting blade
drive and wheel drive are turned off! The machine drive parts could be damaged (V-belt, belt pulley, clutch pulley, etc.)!
2.4.3 Work with the machine
2.4.3.1 Cutting width
Always adjust the cutting width to the stand density!
It is not recommended to use the maximum cutting width (
Table 3
) given by the disc construction. In a terrain, the user cannot operate the cutter
straight, and precisely enough to cut the brushes in complete cutting width. We recommend to use the cutter partially (approximately 5-10 cm from the
edge of the plastic front cover) in the cut stand (as shown in
Pict.4
from the user’s point of view).
2.4.3.2 Methods of stand cutting
Remove any solid parts form the stand before cutting (such as stones, wires, loose construction leftovers, etc.), as these could be thrown
away or damage the machine. If these cannot be removed, avoid them.
It is necessary to keep the lower disc sliding across the land without bouncing off when cutting in uneven terrain. Disc bouncing causes low quality
stand cutting and uneven stubble.
Let the engine and cutting disc spin in their maximum rpm, and start moving against the stand you wish to cut. The cutting disc throws cut stand onto
the right side, where it is windrowed by the side screen.
➢
Always keep the cut brush on the left side form the machine when cutting (
Pict.4
).
➢
When cutting on slopes it is best to move along the slope contour line.
Keep the safe climbing ability (
Table 3
)!
In case the cut stand is too dense, inter grown, rotten, or flattened, it is necessary to adjust the machine cutting width, so that the cutting disc rpm
would not be too low, and thus causing low cutting quality.
2.4.3.2.1
Cutting problems
Be especially careful when lifting and reversing the machine!
Always turn the engine off when cleaning the space under the top cover!
Always tip the machine backwards on its handlebars only. Always be especially careful when moving in the space under a lifted
machine. Secure the cutter from spontaneous movement!
Always be especially careful when cleaning the space under the top cover. The cutting blades are sharp. Use work gloves, or other
convenient objects, e.g. a piece of branch, for cleaning the machine.
Before continuing any activity on the machine or its surroundings, always wait until the cutting disc stops.
1.
The cutting disc and the engine rpm are both slowing down, but the engine does not stall.
➢
Stop the machine immediately, reverse slightly while lifting the front of the machine a bit (by pressing the handlebars down). The
space under the top cover partially cleans itself from extensive amounts of grass mass. Start moving against the stand again.
2.
Cutting disk stopped spinning, the engine staled.
➢
Release both handlebars levers and lift the cutter by pressing the handlebars. Move the cutter slightly backwards. Clean the space
under the top cover, and spread the cut grass across the surface. Start the engine, turn the cutting disc drive on, and start moving against
the stand again.
3.
The cut brushes keeps catching on the side screen
(because the stand is too thick).
➢
Stop the cutter and turn the engine off. Dismount the side screen and put it in a safe place, out of the cut area, so that it cannot be
stolen.
2.5 Maintenance, servicing and storage
The weight of the cutter requires two persons for carrying out its maintenance and adjustment.
