How To Remove The Battery (Figure 4)
To charge or clean the battery (1), remove the
battery (1) from the unit as follows.
WARNING: To prevent sparks, dis-
connect the black battery cable (8)
from the negative (-) terminal be-
fore you disconnect the red cable (5).
WARNING: The battery contains
sulphuric acid which is harmful to
the skin, eyes and clothing. If the
acid gets on the body or clothing, wash
with water.
1. Disconnect the black cable (8) from the
negative (-) terminal.
2. Disconnect the red cable (5) from the posi-
tive (+) terminal (4).
3. Lift the battery tray (3) and the battery (1)
out of the unit.
How To Charge The Battery (Figure 4)
WARNING: When you charge the
battery, do not smoke. Keep the
battery away from any sparks. The
fumes from the battery acid can cause an
explosion.
1. Before you charge the battery (1), remove
the battery (1).
2. To charge the battery (1), use a 12 volt bat-
tery charger. Charge at a rate of 6 amperes
for 1 hour.
3. Install the battery (1).
WARNING: To prevent sparks,
fasten the red cable to the positive
(+) terminal before you connect the
black cable.
4. Fasten the red cable (5) to the positive (+)
terminal (4) with the fasteners as shown.
5. Fasten the black cable (8) to the negative
(-) terminal with the fasteners as shown.
How To Adjust The Gauge Wheels
The axle bolts for the gauge wheels were
mounted in the LOW cut position. To change the
position of the gauge wheels, move the axle
bolts as follows.
IMPORTANT: Before you adjust the gauge
wheels, you must do the following. Make
sure the mower housing is level. Make sure
the height of cut is set at the height you want
for your lawn. Mow a short distance on a flat
level area and look at the area that was cut. If
the mower housing does not cut level, see
the instructions “How To Level The Mower
Housing.”
WARNING:
Before you make an
inspection, adjustment, or repair to
the unit, disconnect the wire to the
spark plug. Remove the spark plug wire to
prevent the engine from starting by acci-
dent.
1. (Figure 22, illustration “I”) Remove the
gauge wheels (12) and axle bolts (11).
2. (Figure 13) Mow a short distance on a flat
level area to check the level of cut and the
height of cut. Look at the height of cut posi-
tion number (3) on the lift lever (1).
3. (Figure 22, illustration “I”) Look at each
gauge wheel bracket (13). There are 3
holes in each bracket and a number next to
each hole. The number for the height of cut
position on the lift lever indicates the correct
hole to use on each gauge wheel bracket
(13).
NOTE: Wheel bracket hole number 1 is
equal to lift lever position number 1,
Wheel bracket hole number 2 is equal to
lift lever position number 2, Wheel
bracket hole number 3 is equal to lift lever
position numbers 3,4,5,6.
4. Assemble the axle bolts (11) to the gauge
wheel brackets (13) using the correct hole
in the bracket as indicated.
NOTE: If the height of cut position is
changed by the lift lever, you must move the
gauge wheels to the correct hole to keep a
level height of cut.
How To Level The Mower Housing
(Figure 13 and Figure 14)
If the mower housing is level, the blade will cut
easier and the lawn will look better.
WARNING: Before you make an in-
spection, adjustment, or repair to
the unit, disconnect the wire to the
spark plug. Remove the spark plug wire to
prevent the engine from starting by acci-
dent
1. Make sure the unit is on a hard flat surface.
2. Check the air pressure in the tyres. If the air
pressure is incorrect, the mower housing will
not cut level. Make sure the tyres are inflated
to: Front Tyres 0,97 BAR (14 PSI), Rear
Tyres 0,69 BAR (10 PSI).
3. If equipped, remove the gauge wheels.
4. (Figure 13) Move the lift lever (1) to the
level adjustment position (2).
WARNING: The lifter lever (1) is
spring loaded. Make sure the lift
lever (1) is locked in the level ad-
justment position (2).
5. (Figure 14) Loosen the left and right ad-
juster knobs (1). Push down on each side of
the mower housing. Make sure both sides of
the mower housing are setting on a flat sur-
face. Also, make sure the lift links (2) are
loose and can easily move up or down.
6. Push down on the lift links (2) and tighten
the left and right adjuster knobs (1). If
necessary, use a wrench to tighten the ad-
juster knobs (1)
7. (Figure 13) Raise the lift lever (1) from the
level adjustment position (2) to a cutting
height position.
8. If equipped, attach the gauge wheels.
9. Mow for a short distance. If the height of cut
is not level, repeat the above steps.
Where To Lubricate (Figure 15)
Lubricate the areas shown
with engine oil.
Apply grease with a brush to
the areas shown.
Models with grease fittings:
Lubricate with grease gun.
NOTE: Apply grease to the steering gear as-
sembly.
CAUTION: If the unit is operated in dry areas
that have sand, use a dry graphite spray to
lubricate the unit.
Check The Tyres
Check the air pressure in the tyres. Tyres with
too much air pressure will cause the unit to ride
rough. Also, the wrong air pressure will keep the
mower housing from cutting level. The correct
air pressure is: Front Tyres 0,97 BAR (14 PSI),
Rear Tyres 0,69 BAR (10 PSI).
How To Replace The Motion Drive Belt
1. Remove the mower housing. See the instruc-
tions on “How To Remove The Mower Hous-
ing”.
2. (Figure 16) Remove the mid-idler pulley
(4).
3. Disconnect the idler spring (7).
4. Remove the idler pulley (8) and spacer (9).
5. Remove the V-ilder pulley (5) and spacer
(13).
6. Remove the motion drive belt (1) from the
drive pulley (6).
7. (Figure 17) To remove the motion drive belt
(1) from the stack pulley (2), pull the front
end of the belt under the stack pulley (2)
and then back between the stack pulley and
the steering plate (3).
8. (Figure 11) Remove the access panel (10).
9. Remove the two screws (11) that attach the
steering shaft assembly (12). Raise the
steering wheel and steering shaft assembly

above steps.
12. (Figure 16) Check the routing of the motion
drive belt (1). Make sure the motion drive
belt is installed correctly on the idler pulleys.
