observed, do not operate until leakage is fixed.
To check the transmission oil level:
1. Move the unit to a level area. Stop engine and lock
brakes.
2. Raise the seat plate.
3. Remove the check plug. Oil level should be at the top
of the Check Tube (Figure 7).
To add oil:
1. Remove breather. Add oil to fill tube until oil level can
be seen in check tube.
2. Replace breather and check plug.
IMPORTANT: To prevent severe damage to transmission,
always maintain proper oil level.
Check oil daily after changing transmission oil and/or
filter. Add oil if necessary. Continue daily checks until oil
level is stable.
Transmission Oil Filter
The transmission oil filter should be changed after the
first 50 hours of operation. Change the transmission oil
filter every 100 operating hours thereafter. It is not
necessary to change transmission oil each time the filter
is changed. Change the transmission oil with every fifth
transmission oil filter change (Figure 8).
To change the transmission oil filter:
1. Position unit on a flat level surface.
2. Place a container under filter to catch oil spillage as
filter is removed.
3. Use an oil filter removal tool to unscrew filter. Discard
old filter.
4. Fill new oil filter with fresh, clean, same type oil used
in transmission to saturate the element.
NOTE: Some oil may spill out of filter as it is rotated from
vertical to horizontal position when installing it. Keep
container in place to catch spilled oil.
5. Lubricate gasket with oil and spin filter on threaded
adapter to gasket contact. Hand tighten additional
1/2 to 3/4 turn. DO NOT OVERTIGHTEN.
6. Fill transmission with new oil.
7. Prime the transmission.
Priming the Transmission
IMPORTANT: The transmission must be primed after
changing the oil or oil filter to prevent internal
transmission damage.
To prime the transmission:
1. Remove implement plug, spring and cone. Pour one
pint of oil in port. Replace cone, spring and tighten
plug (Figure 9).
2. Run engine for 2-3 minutes.
3. Check for oil leaks at filter and plug.
4. Check oil level. Add as necessary.
5. Repeat steps 2-4.
Transmission Cooling System
Debris accumulating on cooling fins on outside of the
transmission causes overheating. Check fins and clean
every fifty (50) operating hours. Check more often under
dusty, dirty conditions.
Transmission Neutral
The direction control pedal should return to neutral after
foot pressure is removed. If the unit creeps while in
neutral, the neutral stop mechanism may need adjusting
(Figure 10).
CAUTION
Before changing the filter, place turn ignition “Off”,
remove key and engage parking brake.
