Operating Instructions

Suspension Seat
A fully adjustable suspension seat is standard. This
seat is adjustable for back pitch, weight, lumbar sup-
port and armrest inclination. Proper adjustment for
each operator is essential to safe operation and op-
erator comfort.
Read operating instructions in full before you use
the seat.
NOTE:
Driver seats that have been adjusted incor-
rectly have little or no vertical travel with the operator
in the seat. To prevent damage to the driver’s back
and to the seat, the seat must be adjusted for the
driver’s weight
before use
and
before every
change of driver.
To prevent injury,
no objects
should be placed within the moving area
of the
driver seat.
CAUTION
To eliminate any risk of accident, the set-
tings must be checked to ensure they are
correctly engaged before the mower is
driven.
Adjustments must
not
be made
while driving.
If you make any changes to the suspension seat
(for example fitting parts which are not original
GRAMMER
parts) it may no longer meet the safety
standards to which it is tested.
Functions may be
impaired,
threatening your
safety.
For this reason,
any change in design of the seat
must be ap-
proved by
GRAMMER (Seat Manufacturer).
IMPORTANT:
Fasteners must be
checked regu-
larly for tightness.
If the seat wobbles there may
be loose bolts or other faults.
If you note that the seat does not function correctly
(for example a defective seat suspension; improper
curving of the lumbar support or damaged bellows),
contact your Walker dealer immediately
to ar-
range for repairs to be carried out. If you fail to do
so, your health may be affected and the
risk of ac-
cident increased.
CAUTION:
Before the tractor is used, the safety
switch must be checked for
proper function.
The
operation of the switch is checked by having the op-
erator lift off the seat with the tractor moving forward
and/or the blades engaged -- this action should
cause the machine to stop. If a malfunction is de-
tected the tractor must not be driven, it should be
repaired or replaced before operating the mower.
CAUTION
Except for the driver’s weight during nor-
mal use, no loads must be placed on seats
with a built-in switch detecting seat occu-
pation, as the vehicle may otherwise start
to move by itself.
For armrest inclination adjustment,
the inclina-
tion of the armrests can be modified by turning the
adjustment knob. Refer to
Figure 1.
Turning the knob to the right lifts the armrest in front,
turning it to the left, lowers it in front.
For weight adjustment,
the weight of the respec-
tive driver must be set while sitting on the seat. Fold
out the weight adjustment handle completely, hold it
at the front and move it upwards or downwards
(10 movements from minimum to maximum).
Before every new movement, bring the handle back
to the starting position (audible locking sound). The
driver’s weight has been set correctly, when the ar-
row is in the middle of the viewing window. Refer to
Figure 2.
IMPORTANT:
To prevent injury to the operator and/
or damages to the seat, the setting for the driver’s
weight must be checked and adjusted as necessary
before the mower is driven.
When the minimum/maximum weight adjustment
has been reached, you will notice an empty move-
ment in the handle.
When you have set the weight, fold the handle com-
pletely into the locking position.
