MAINTENANCE
ENGINE - KAWASAKI
The maintenance schedule detailed is for average operating conditions. Under extreme conditions (dusty,
dirty or more than 8 hrs continuous use) maintain more frequently.
Cooling Fins and Air Intake screen (daily)
Ensure that the cooling fins and air intake screen
W are cleaned daily. Continued operation with
a clogged cooling system will cause severe
overheating and result in engine damage. You can
use compressed air to clean.
Air Cleaner
Dual element air cleaners have a paper air cleaner
element Z with an oiled, foam precleaner element V
on the dirty side of the paper element. Both should
be inspected regularly and maintained.
Clean and re-oil precleaner element every 25 hours
(more often under dusty conditions).
1. Turn knobs 1/4 turn counter-clockwise to remove
air cleaner cover F.
2. Loosen clamp X to remove air cleaner assembly.
3. Remove and wash precleaner V with kerosene or
liquid detergent and water.
4. Wrap precleaner V in a cloth and squeeze to
remove excess cleaning agent.
5. Saturate precleaner V with new engine oil and
squeeze to remove excess oil.
Every 100 hours (more often under very dusty or dirty
conditions), check the paper cartridge Z.
– Clean by tapping gently.
– Do not wash the cartridge or use compressed air
– Replace when cartridge is dirty, bent or
damaged.
6. Reinstall precleaner V over paper cartridge Z,
reinstall air cleaner assembly, tighten clamp X,
and reinstall cover F.
15
MAINTENANCE
Hydro
Midsize
Blade Sharpening
Blades may be sharpened by filing or grinding, but with either method the balance of the blades must be
maintained at 5/8 oz/in or less. Failure to maintain balance causes excess vibration, wear and shortened life
of not only the blades, but most all components of the machine. To balance a blade after sharpening: attach
1/8 oz of weight 5" from center on the light end. This should make the light end the heavy end. If it does not:
File or grind the heavy end until the addition of weight makes the light end the heavy end.
NOTE:
 Do not overheat or weaken the blades.
 Do not straighten bent blades. Replace with new
BOB-CAT blades.
If lift portion of blade is worn thin replace with a
new BOB-CAT blade.
 ALWAYS replace with BOB-CAT blades—do not
use another manufacturer’s blades as this could
be dangerous.
 Replace cracked or bent blades.
BLADE REMOVAL
1. Use a box wrench or socket with a long breaker
bar to remove spindle bolt under cutterdeck.
2. Slip tube over breaker bar or wrench if necessary
to gain leverage.
3. Keep hands clear as blades may rotate when bolt
releases.
4. When changing blades, wear thickly padded
gloves.
5. Block blades from turning by using a piece of
wood.
6. Follow these instructions to prevent injury when
bolt releases.
NOTE: To prevent blade from turning, place block of
wood at A, with grain perpendicular to blade.
BLADE RE-INSTALLATION
1. Place the desired number of spacers (no more
than 2) on the spindle bolt below the cutterdeck
between the blade and spindle shaft.
2. Insert the cutter spindle bolt (from bottom) complete with washer, blade and spacers.
3. Place remaining spacer(s) on the spindle bolt
above the cutterdeck between the conical washer
and nut (as shown). Replace nut and tighten to
70 ft-lbs.

MAINTENANCE
Spark Plug
 Remove plug and check condition.
 Good operating conditions are indicated if the plug has a light grey or tan deposit. A white blistered coating may indicate overheating. A black coating usually means an “over rich” fuel mixture caused by a
clogged air cleaner or improper carburetor adjustment. Do not sandblast, wire brush or otherwise try to
clean a dirty plug. Best results are obtained with a new plug.
 See engine manufacturers manual for proper spark plug gap.
HYDRAULIC RESERVOIR
CHECK, DRAIN AND FILL
Check level every 100 hours or when a leak has occurred. To check level: Remove reservoir cap. Add
10W30 oil until the oil level reaches the bottom of the
filler tube. Do not overfill.
EVERY 500 HOURS:
Change hydraulic oil and filter. Remove plug D to
drain reservoir. Remove and replace filter. Filter is
located on front of tank at G. Reinstall plug and fill
with 10W30 oil to the bottom of the filler tube F.

ADJUSTMENTS
Hydro
Midsize
NOTE: Make all adjustments with the engine shut off, spark plug wire disconnected and mower drive disengaged.
TRACTION DRIVE HYDROSTAT ADJUSTMENTS: The following adjustments must be done in order.
Step 1 - Set Neutral
Neutral is set at the factory. If it should require
adjustment, raise the wheels off the ground by setting
the machine on jackstands or blocks. Disconnect
the traction control rod A and speed control rod R
at each pump end. Disconnect pump arm spring U
from bolt on engine deck. Loosen bolt S securing the
neutral plate eccentric shaft just enough to turn the
shaft. Start the engine and run at low speed. Turn
eccentric shaft T to raise or lower the point at which
the follower bearing is held in the center of the “V”
until the wheels stop turning. Tighten the eccentric
shaft bolt. Increase the throttle setting and check the
adjustment. Readjust if necessary. Shut the engine
off before proceeding to steps 2 and 3.
STEP 2 - Adjust Speed Control Rods
First adjust neutral, as outlined in Step 1. Set speed
control levers to neutral. Adjust swivels on lower
ends of speed control rods R so they just go into the
top of the slots on the neutral plates.
NOTE: If the speed control levers do not have
adequate tracking adjustment, the swivel on one of
the rods needs to be turned 1 turn.
Step 3 - Adjust Traction Levers
Set neutral and adjust speed control rods as outlined
in Steps 1 and 2. Set traction locks in the neutral
position. Grasp traction rod A and pull down on it to
take out any slack. The pump control arm has some
back and forth play. Adjust the swivel to the center
of the control arm play. Connect the swivel to the
control arm. Reattach pump arm spring U to bolt on
engine deck.
NOTE: More reverse speed may be gained by
adjusting the swivel to the rear of the control arm
play. A minimum of 1/16" play is required so the

ADJUSTMENTS
Speed Control Lever Friction
The speed control lever is held where set by friction
pads. If the setting will not hold, tighten nuts E to
increase friction on the speed control lever.
Adjust Knob D to get machine to track in a straight
line.
PARKING BRAKE - Apply parking brakes and open
the bypass valves on the hydraulic pumps. Try to
push the machine forward. If wheels rotate, adjust
brakes as follows.
TO ADJUST:
1. Remove the hairpin cotter A from the brake rod
at the brake lever as shown.
2. Slide the brake rod out of the brake lever and
turn the rod in or out of the brake swivel B as
needed.
NOTE: The brake should initially be adjusted so
that the brake rod extends through swivel B 1" as
shown. If more brake pressure is required adjust
as necessary.
3. Reassemble brake rod to the brake lever using
hairpin A.
4. Apply parking brakes and try to push the machine
forward. If wheels rotate, readjust brakes.
5. Close bypass valves on the hydraulic pumps.

ADJUSTMENTS
OPERATOR PRESENT CONTROLS
The operator present (OP) controls should be adjusted to control the operation of the plunger of the
operator present switch (located under the right side
of the control panel). Depressing OP levers F should
depress the plunger; releasing the levers should
extend it.
TO ADJUST:
1. Loosen clamp bolts G on both ends, so clamps
can rotate on shaft.
2. Rotate actuator lever to depress switch plunger.
Keep OP levers against handles and tighten bolts
G.
3. When released, the OP levers should rise and
the actuator lever should rotate away from the
switch, allowing the switch plunger to extend
completely.
HANDLE BAR HEIGHT ADJUSTMENT
To adjust handle bar height: Remove bolts G and
loosen bolts E on each side of handlebars. Raise
or lower as required. Reposition upper handle and
reinsert bolts G into appropriate hole in lower handle
and tighten. Readjust traction control rods, parking
brakes and speed control rods.
