6. Raise the rear of machine up and support with
jack stands (or equivalent support) just high
enough to allow drive wheels to turn freely.
7. Start engine and move throttle control ahead to
full throttle position. Move the speed control
levers to the full speed and run for several
minutes. Shut down machine and recheck oil
level.

it is felt the oil has been contaminated or been
extremely hot.
Changing oil unnecessarily could damage hydraulic
system by introducing contaminates into the system.

Check Engine Coolant Level

Service Interval: Before each use or daily
Note: If the engine coolant level is below the
indicator line on the overflow bottle when the
engine is cold, the coolant temperature gauge may
not register correctly during operation and/or
the warning buzzer may not sound if the engine
overheats.
1. Stop engine and wait for all moving parts to stop.
Make sure unit is on a level surface.
2. Check with engine cold.
3. View coolant level in overflow bottle on the left
side of the engine compartment. Coolant level
should be at the indicator line on the overflow
bottle.
4. If the coolant level is low, open hood or raise
radiator, remove the cap to the overflow bottle
and fill to the indicator line. Units should only be
filled with a 50/50 mix of Dex-Cool© extended
life coolant and water. Dex-Cool© can be
identified by its orange color.

Engine coolant is hot and pressurized and
radiator and surrounding parts are hot. Spray or
steam from hot, pressurized liquid in the engine
cooling system and touching a hot radiator may

Allow the engine to cool completely before
removing the radiator cap or servicing any
component of the cooling system.
