Hydraulic Oil
NOTE: Use only 5W-50 or 15W-50 all synthetic oil.
Checking Hydraulic Oil Level
1. Park machine safely. (Refer to Parking Safely in SAFETY
section.)
MX20114
2. Clean area around reservoir dipstick cap (A).
3. Remove dipstick cap (A). Wipe dipstick clean.
NOTE: Do not tighten dipstick cap when checking oil level.
4. Insert dipstick into reservoir filler neck (B). Do not tighten cap.
5. Remove dipstick. Check oil level on dipstick. Oil level should
be in crosshatch area between ADD and FULL marks.
• If oil is low, add oil to bring oil level no higher than FULL mark
on dipstick.
• If oil is above FULL mark, drain oil to proper level.
6. Insert dipstick. Tighten cap.
Changing Hydraulic Oil and Filter
1. Park machine safely. (Refer to Parking Safely in the SAFETY
section.)
2. Allow engine and hydraulic oil reservoir to cool.
MX13362
3. Clean area around reservoir dipstick cap and oil filter.
4. Turn oil filter (B) counterclockwise to remove.
5. Allow hydraulic oil to drain into a drain pan with a capacity of at
least 3.8L (1.0 gal).
6. Apply a film of clean hydraulic oil to gasket of new filter.
7. Install new filter. Turn filter clockwise until gasket makes
contact with mounting surface. Tighten 1/2 to 3/4 turn after
gasket contact.
8. Remove dipstick cap from hydraulic reservoir filler neck.
NOTE: Dry fill capacity for hydraulic system is 3.1L (3.3 qt).
9. Fill oil reservoir with approximately 1.9L (2 qt) of oil.
10. Insert dipstick. Tighten cap.
11. Start engine.
12. Move throttle lever to 1/2 to 2/3 position.
13. Unlock park brake.
14. Cycle motion control levers forward and rearward several
times. Check for leaks around filter.
15. Stop engine. Check oil level. Add oil as necessary to bring oil
level to FULL mark on dipstick.
SERVICE AND ADJUSTMENTS
WARNING: AVOID INJURY. Read and understand entire
Safety section before proceeding.
IMPORTANT: Avoid Damage! Check oil level in reservoir tank
when oil is cold.
Do not overfill oil reservoir tank. Oil will expand during
operation and could overflow.
CAUTION: Avoid injury! Escaping fluid under pressure
can penetrate the skin causing serious injury. Avoid the
hazard by relieving pressure before disconnecting
hydraulic or other lines. Tighten all connections before
applying pressure. Search for leaks with a piece of
cardboard. Protect hands and body from high pressure
fluids.
Use caution when filling and draining hydraulic oil. During
periods of machine operation the hydraulic oil reservoir
can get hot. Allow engine and oil reservoir to cool before
servicing.
IMPORTANT: Avoid Damage! Contamination of hydraulic fluid
could cause transmission damage or failure. Do not open oil
reservoir cap unless absolutely necessary.
Severe or unusual conditions may require a more frequent
service interval.
IMPORTANT: Avoid Damage! Do not add oil beyond FULL
mark. Oil capacity after draining may be less than dry fill
capacity. Check oil level before filling completely.
CAUTION: Avoid injury! Help prevent serious bodily
injury. Remain alert to other people and the surroundings
when operating the machine.
