Maintenance; Hydraulic Fluid Repair - Waterous K Series Operation And Maintenance Instruction

Advertisement

An oil splash system, within the gear case, lubricates the gears and other
moving parts. Check oil level monthly by removing the square head pipe
plug on side of gear case marked OIL LEVEL. The oil should be level with
the bottom of the hole.
NOTICE
If foil level is low, locate the source of the leak and repair. If the
oil level is high, loosen the drain plug until the oil drops to the
proper level. If excessive water drains out, change the oil and
determine the source of the water leakage and repair.
CAUTION
NOTICE
Oil temperature hazard.
May cause premature seal wear and
Oil temperature should not exceed 250 for an extended period
of time in order to prevent seal wear and damage.

To add oil, remove filler plug or breather at top of gear case, and pour oil
through opening until oil comes out the oil level hole. DO NOT OVERFILL.
Use SAE 80w-90 gear oil.
Drain gear case by removing magnetic drain plug from bottom, and refill with
new lubricant after each accumulated 100 hours of pump operation, or at
least every spring and fall. (Under severe service conditions, where pump
has been used continuously at high output, change oil more frequently.)
The capacity is approximately 2-1/4 quarts. Be sure to clean drain plug and
breather.
Hydraulic Fluid Reservoir
Keep the fluid reservoir of the hydraulic power unit filled. The capacity is 1/2
quart. Drain and replace the fluid only if it becomes dirty or contaminated. Use
ATF (Automatic Transmission Fluid) or equivalent.
Annually check accumulator's gas pre-charge pressure.
1. Bleed off hydraulic system pressure.
2. If the gas precharge pressure is below 100 psi., the
accumulator should be replaced.
