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 gear oil lubricant 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:
