CLEAN THE WATER PUMP
Keep the water pump set clean and free of foreign material. Please check pump after water pump
stop on each time and clean pump if pump with foreign material.
CHECK GEARBOX OIL LEVEL
Check gearbox oil level before you first use it. Thereafter, check gearbox oil level every 10 hours
of operation or once weekly, whichever comes first. To check oil level, proceed as follows:
1. Make sure the water pump is as level as possible.
2. Remove the OIL LEVEL CHECK PLUG from the water pump gearbox (Figure 6).
Figure 6 -- Gearbox Oil Servicing Points
3. Check oil level. Oil should be at point of overflowing the OIL LEVEL CHECK PLUG opening.
If necessary, add SAE 90 GEARLUBE oil to the recommended level. See "CHANGE GEARBOX
OIL."
4. When oil level is correct, install and tighten the OIL LEVEL CHECK PLUG.
CHANGE GEARBOX OIL
Change gearbox oil after the first 25 hours of operation. Thereafter change gearbox oil every 250
operating hours or every six months, whichever occurs first. To change gearbox oil, proceed as
follows:
1. Operate the water pump until gearbox oil is thoroughly warmed up (about 30 minutes), then
shut down.
2. Immediately after shutting it down, remove gearbox oil drain plug (Figure 6). Drain oil
completely into a suitable container. Remove oil fill/breather and oil level check plug to facilitate
draining.
3. After all oil has drained, install and tighten oil drain plug.
4. Add SAE 90 gearlube oil through oil fill/breather opening, until oil just starts to overflow from
oil level check plug opening. Pour slowly.
5. When oil level is correct, install and tighten oil fill/breather and oil level check plug.
