Information.
DANGER: Comply with all safety rules, read all warning and caution decals and tags affixed to
the water pump. Failure to obey safety rules may result in personal injury or death.
BEFORE USING YOUR WATER PUMP
WARNING: This water pump requires a certain horsepower to drive when full capacity loads
are being powered through unit. This horsepower is applied to water pump as torsional or
twisting force. Such a high twisting force can tip over water pump with considerable force as
soon as you apply water suction. This could cause personal injury or damage to equipment.
1. Use ONLY a 540rpm power takeoff drive operating speed. Any attempt to operate the water
pump set with higher power takeoff speeds will result in damage to equipment or personal injury.
2. Make sure the water pump fill full water before starting and has been properly prepared to
use
CHECK GEARBOX OIL LEVEL
Before using the water pump, check gearbox oil level. See "Maintenance" section on page 10.
CONNECTING THE POWER TAKEOFF SHAFT
Connect the PTO shaft to the tractor PTO drive system and to the water pump's gearbox shaft.
The shaft must be fully engaged with both the tractor and the water pump shaft. The water

pump and tractor shafts must be parallel as viewed from the top and sides of the shaft. Maintain
PTO shaft joint angles (Figure 2) equal and as small as possible.
For Smoothest Operation Keep Tractor Shaft and Gearbox Shaft Parallel (Side and Top Views),
Keep Joint Angles Equal & Small as Possible.
CAUTION: Make sure the water pump's PTO shaft guard is properly attached to the gearbox
before starting.
