Radiator and Cooling Fans
Always check and clean the radiator fins at the intervals
outlined in the Maintenance Schedule.
Unauthorized attachments or accessories that have been
installed in front of the radiator or behind the cooling fans
may obstruct or deflect the air flow through the radiator. This
can cause overheating and engine damage.
NOTE: Using a high pressure washer to clean the vehicle
could damage radiator fins which can impair the radiator's
effectiveness.
Radiator Overheating
If the coolant in the radiator overheats follow these steps:
1. Park the vehicle outside in an open area.
2. Place the gear select lever in the "NEUTRAL" position.
3. Engage the park brake.
4. Allow the engine to idle for 5 minutes.
5. Do not open the hood or access the radiator area until
the coolant has cooled down. Make sure there is no
steam coming from the radiator area before proceed-
ing.
6. After the coolant has cooled, consult the Troubleshoot-
ing section of this manual to assist in determining the
cause of the overheating.
7. Fix the problem before continuing operation. If the
problem can not be found, contact your Hustler
Dealer. Do not operate the vehicle until the issue is
resolved.
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 recommenda-
tions, bolt torques, etc. The engine warranty is backed by the
engine manufacturer. Special attention should be paid to
applicable data which will not be duplicated here.
CVT Belt
Inspect the CVT belt and drive pulley grooves annually for
wear or damage. Replace the belt after every 500 hours of
use or every 3 years, whichever comes first. Replace the
drive pulleys if any sign of wear or damage occurs.
Replace the belt if it shows signs of:
• severe cuts
• tears
• separation
• weather checking
• cracking
606653
• burns caused by slipping.
If the CVT belt fails, loss of traction control will
occur especially when operating on a slope. If you
lose traction control while operating the vehicle:
• Steer the vehicle to a flat surface, if possible,
while using the brakes to control speed.
• Stop the vehicle, engage the park brake,
place the gear select lever in the NEUTRAL
position, shut the engine off, and remove the
key from the ignition switch,
• Inspect the vehicle and involve your Hustler
Dealer to resolve the problem before continu-
ing to operate.
Brakes
Checking the Brake Fluid Level
Routinely inspect the brake system. Inspect the brake fluid
level per the Maintenance Schedule section.
Use DOT3 brake fluid only in the Hustler
tem.
Other types of brake fluid or oil will ruin synthetic
resin or rubber brake components which can
®
cause brake failure.
Never operate the vehicle if the brake fluid is below
the "MIN" mark in the reservoir.
• Avoid contamination of the brake fluid. Thor-
oughly clean area around the filler cap before
removing. Do not open the brake fluid reser-
voir cap unless absolutely necessary.
• Use extreme care when filling the reservoir. If
brake fluid is spilled wash it off with water
immediately.
To check the brake fluid level:
1. Stop the vehicle on a level surface.
2. Set the gear select lever in the "NEUTRAL" position.
3. Engage the park brake.
4. Shut the engine off.
5. Remove the key from the ignition switch.
6. Open the hood.
7. Locate the brake fluid reservoir. It is on the left side in
front of the dash.
8. Check the brake fluid level in the reservoir. It should be
above the "MIN" marks.
