replacement parts is an “alteration” and will not be considered for warranty
in the event of engine damage.
Recommended service procedure
1. Release clamps and remove element. Clean the canister with a damp
cloth.
2. Before installing a new element, inspect it by placing a bright light
inside and rotate the element slowly, looking for any holes or tears in
the paper. Also check gaskets for cuts or tears. Do not attempt to
use a damaged element which will allow abrasive particles to enter
the engine.
3. Reinstall the dust cup. Make sure it seals all the way around the air
cleaner body, then tighten the clamps.
4. Check all fittings and clamps periodically for tightness and inspect
hoses for holes or cracks.
5. Periodically check the intake hose for signs of ingested dust. Locate
and repair the source of ingested dirt.
6. Never operate a machine without an air filter installed.
Air restriction indicator
Any unit with a Kohler or Kawasaki engine will have an air restriction
indicator installed in the air cleaner. Fig. 10-11
Replace the element whenever the restriction indicator shows reaches the
change filter red line. Check the indicator daily and replace element as
needed or annually whichever occurs first.
Reset the indicator by pushing in on the yellow button after each element
change. Fig, 10-11
A restriction indicator takes the guesswork out of air cleaner servicing
and allows you to safely benefit from the filter’s optimum performance.
General engine maintenance
Detailed instructions and recommendations for break-in and regular
maintenance are specified in the Engine Owner’s manual. Please refer to
this manual for engine servicing, lubricating oil levels with quality and
viscosity recommendations, bolt torques, etc. The engine warranty is
backed by the manufacturer. Special attention should be paid to applicable
data which will not be duplicated here.
Belt replacement
Figures 10-12, 10-13 and 10-14 show diagrams and descriptions of the
unit’s belt drive systems.
Inspect these belts frequently for wear and serviceability. Replace a belt
that shows signs of severe cuts, tears, separation, weather checking and
cracking, or burns caused by slipping. Slight raveling of belt covering does
not indicate failure, trim ravelings with a sharp knife.
WARNING: If the pump belt fails, loss of control will occur
especially when operating on a slope. If you lose steering
control while operating the machine, place the steering
control levers in the park brake position immediately. Inspect
the machine and involve your Hustler dealer to resolve the
problem before continuing to operate.
Inspect the belt pulley grooves and flanges for wear. A new belt, or one
in good condition, should never run against the bottom of the groove.
Replace the pulley when this is the case, otherwise belt will lose power and
slip excessively.
Never pry a belt to get it on a pulley as this will cut or damage the
fibers of the belt covering.
Keep oil and grease away from belts, and never use belt dressings. Any
of these will destroy the belt composition in a very short time.
Mower blade maintenance
Check the mower blades daily, they are the key to power efficiency and
well groomed turf. Keep them sharp, a dull blade will tear rather than cut
the grass, leaving a brown ragged top on the grass within a few hours. A
