Working Techniques; Adjusting The Cutting Height - KLIPPO LAWNMASTER Bedienungsanleitung

Controls
Throttle control
The throttle control lever is located in the middle on the up-
per handle. To start a cold engine, push the throttle control
lever forward and move the choke lever situated on the
carburettor to fully on position. After starting, slowly move
the choke lever to the run position. Do not use the choke
when starting warm engine. Note that the engine speed
dictates the speed and operation of travel and cutting reel.
Reel clutch lever
The reel clutch lever (A) is sprung to the disengage posi-
tion. Squeeze the lever toward the handlebar to engage
the drive to the cutting cylinder. Release the lever to disen-
gage the drive to the cutting cylinder.
A
Drive clutch lever
The drive clutch lever (C) is sprung to the disengage po-
sition. Squeeze the lever toward the handlebar to engage
the drive to the rear roller. Release the lever to disengage
the drive to the rear roller.
Starter handle
The motor is started by pulling the starting handle. Grip the
starter handle, slowly pull out the cord with your right hand
until you feel some resistance (the starter pawls grip), now
quickly and powerfully pull the cord. Never twist the starter
cord around your hand.
Handlebar
The clutch cables and levers are factory fi tted to the upper
handle and mower. Mount the upper handlebars onto the
mower using the supplied bolts, and make sure that the
tongue on the lower handlebars slides into the slot on the
upper handlebars. The height and position of the handlebar
may be changed to suit individual operators requirements
by loosening the bolts retaining the lower handlebar to the
mower frame and pivoting it in the slot provided. The nuts
and bolts must be secured in the position required.

Adjusting the cutting height

The cutting height is gauged by the position of the front
and rear rollers. It is variable between 7 - 30mm and
adjusted by means of a plastic handwheel (2 wheels on
the Golf model). The cutting height is increased by rotating
the handwheel in a clockwise direction and vice-versa. If a
particular cutting height is required it is necessary to bridge
the rear and front rollers and measure the normal height
to the cutting point of the bottom blade and adjusting the
handwheel to obtain the correct height of cut.

Cutting cylinder to bottom blade adjustment
It is essential that the relationship between the bottom
blade and cutting cylinder is kept in good adjustment
and that cutting edges are kept sharp to ensure good
cutting performance, minimum power consumption and
prolonged life for the cutting edges. Carry out the following
procedures before commencing work and re-check the
settings every 2-3 hours of mowing or when the cutting
performance is noticeably reduced.

Cutting system
Check that the cutting cylinder is correctly set in relation
to the bottom blade by a piece of 0.05 mm (2 thou) shim
between the cutting cylinder and the bottom blade. Care-
fully rotate the cylinder by hand and check that the shim
is being touched by points along the length of the blade.
Hold the shim fl at on the bottom blade.
If adjustment is necessary, proceed as follows:
Turn adjusting screw (A) in a clockwise direction each end
alternatively, whilst rotating the cutting cylinder, with the
shim on the bottom blade and is in fl eeting contact with
the cutting cylinder along its entire length. Re-check this
procedure making marginal adjustments to screw (A) as
necessary.
NOTE! There should always be a clearance of 0.05 mm
(2 thou) between the bottom blade and cutting cylinder to
create a scything cut for a better fi nish. This clearance also
eliminates the noise created by the blades. DO NOT over
tighten the bearing housing retaining nyloc nuts (B) and (C).
When the grass is not being cut cleanly it will be necessary
to regrind the front of the bottom blade. This procedure
must be carried out by your authorised service agent on a
quality, well maintained bottom blade grinding machine. If
the wearing is excessive both the cutting cylinder and bot-
tom blade will need regrinding.
Catcher
Always shut off the engine whilst fi tting or removing the
grass catcher. The lawn mower can be operated with the
grass catcher fi tted or removed. Generally the quality of
sward will be improved with the grass catcher removed,
hence re-clipping the grass. To fi t the grass catcher,
position the catcher in front of the mower and support the
catcher by its front handle and its top edge. Lift the catcher
into position engaging the hooks over the catcher studs at
each end of the mower frame. Finally lower the catcher into
place, ensuring it is sitting level on the mower. Reverse this
procedure to remove the catcher.
