Checking the Auger Gearbox
Oil Level
Service Interval:
Yearly—Check the auger gearbox oil
and add oil if necessary.
1. Move the machine to a level surface.
2. Clean the area around the pipe plug (Figure 49).
Figure 49
3. Remove the pipe plug from the gearbox.
4. Check the oil level in the gearbox. The oil should be
at the point of overflowing at the filler opening.
5. If the oil level is low, add GL-5 or GL-6, SAE 85-95
EP transmission oil to the gearbox until the point
of overflow.
Note:
Do not use synthetic oil.
6. Install the pipe plug in the gearbox.
Changing the Engine Oil
Service Interval:
After the first 5 hours—Change the
engine oil.
Every 50 hours—Change the engine
oil. Change the engine oil every 25
operating hours when operating the
engine under a heavy load.
If possible, run the engine just before changing the
oil because warm oil flows better and carries more
contaminants.
Use automotive detergent oil with an API service
classification of SF, SG, SH, SJ, SL, or higher. Refer to
your engine owner’s manual.
Use Figure 50 below to select the best oil viscosity for
the outdoor temperature range expected:
Figure 50
1.
Using SAE 30 at outdoor
temperatures below 40°F
(4°C) will result in hard
starting.
2.
Using 10W-30 at outdoor
temperatures above
80°F (27°C) may result in
increased oil consumption;
therefore, check the oil
level more frequently in
these circumstances.
