3. Grasp the caster wheel and slide the bolt out
of the fork or pivot arm.
4. Discard the old caster wheel and bearings.
5. Assemble the caster wheel by pushing the cone
bearings and seals, packed with grease, into the
wheel hub, positioned as shown in
6. Slide the spacer into the wheel hub through
the bearings, captivating the spacer inside the
wheel hub with 2 bearing spacers.
Important:
Ensure that the seal lips are not
folded inward.
7. Install the caster-wheel assembly between the
castor fork and secure it in place with the bolt
and locknut.
8. Tighten the locknut until the wheel no longer
spins freely, then back it off just until the wheel
spins freely.
9. Attach a grease gun to the grease fitting on the

Maintenance

Cooling System Safety

•
Swallowing engine coolant can cause poisoning;
keep out of reach from children and pets.
•
Discharge of hot, pressurized coolant or touching
a hot radiator and surrounding parts can cause
severe burns.
– Always allow the engine to cool at least 15
minutes before removing the radiator cap.
– Use a rag when opening the radiator cap, and
open the cap slowly to allow steam to escape.
•
Do not operate the machine without the covers
in place.
•
Keep your fingers, hands and clothing clear of
rotating fan and drive belt.

Coolant Specification

The coolant reservoir is filled at the factory with a
50/50 solution of water and ethylene glycol base
extended-life coolant.
Important:
Use only commercially available
coolants that meet the specifications listed in the
Extended Life Coolant Standards Table.
Do not use conventional (green) inorganic-acid
technology (IAT) coolant in your machine. Do
not mix conventional coolant with extended-life
coolant.

Ethylene-Glycol Coolant
Type
Extended-life antifreeze
Important:
Do not rely on the color of the coolant
to identify the difference between conventional (green)
inorganic-acid technology (IAT) coolant and extended-life
coolant.
Coolant manufacturers may dye extended-life coolant in
one of the following colors: red, pink, orange, yellow,
blue, teal, violet, and green. Use coolant that meets the
specifications in the Extended Life Coolant Standards
Table.

Important:
Coolant concentration should be a
50/50 mixture of coolant to water.
