9. Tighten the dipstick fully before you start the engine.
To replace the engine oil
If the engine is cold, start the engine for 1–2 minutes
before you drain the engine oil. This makes the engine
oil warm and faster to drain.
WARNING: Do not operate the engine
for more than 1–2 minutes before you drain
the engine oil. The engine oil becomes very
hot and can cause burn injuries. Let the
engine become cool before you drain the
engine oil.
WARNING: If you spill engine oil on
your body, clean with soap and water.
1. Park the product on level ground and stop the
engine.
2. Engage the parking brake. Refer to
To engage and
disengage the parking brake on page 12
.
3. Remove all dirt around the oil tank cap.
4. Remove the oil tank cap and the dipstick.
5. Find the drain hose at the right rear part of the
engine.
6. Put a container below the oil drain hose.
7. Remove the oil drain plug.
8. Let the oil run out into the container.
9. Replace and install the oil drain plug.
10. Fill with new oil and do a check of the engine oil
level. Refer to
To do a check of the engine oil level
on page 23
.
11. Install the oil tank cap and the dipstick.
Note:
For safe disposal of used engine oil, refer to
Disposal on page 29
.
To remove air from the hydrostatic
system
You must remove air from the hydrostatic system
regularly to prevent high noise operation, high operation
temperature, component damage, excessive expansion
of hydraulic oil, and decrease of the drive. The first
time that air is removed from the hydrostatic system,
the drive wheels must be set above the ground. You
must also remove air from the hydrostatic system
each time the hydrostatic system has been opened for
maintenance and when hydraulic oil has been added.
1. Make sure that the hydraulic oil level is correct.
2. Disengage the parking brake.
3. Disengage the drive system. Refer to
To disengage
and engage the drive system on page 12
.
4. Start the engine and apply fast idle speed. Refer to
Throttle control on page 4
.
5. Slowly move the control levers forward and rearward
approximately 5 or 6 times. When air is removed
from the hydrostatic system, the hydraulic oil level
will decrease.
6. Set the throttle control to idle speed. Refer to
Throttle control on page 4
.
7. Engage the drive system. Refer to
To disengage and
engage the drive system on page 12
.
8. Slowly move the control levers forward and rearward
for 5 or 6 times.
9. Stop the engine.
10. Do a check of the hydraulic oil level and fill hydraulic
oil if it is necessary.
11. If it is necessary, do the above steps again until all
air has been removed from the hydrostatic system.
When the product operates correctly, all air has been
removed from the hydrostatic system.
Lubrication, general information
• Remove the ignition key to prevent accidental
movements during lubrication.
• Clean the area before you lubricate a part on the
product.
• Use oil when you lubricate with an oil can.
• When you lubricate with grease, use a chassis or
ball bearing grease that prevents corrosion. Remove
unwanted grease after lubrication.
• Lubricate 2 times a week if you operate the product
daily.
• Do not spill lubricant on the drive belts or the
grooves of the belt pulleys. If you do spill, clean with
alcohol. If the friction between the drive belt and the
pulley is not sufficient after you clean with alcohol,
replace the drive belt.
