GOOD PRACTICES
The introduction of foreign material into the hydraulic
system will result in poor performance and repair
downtime. To avoid this, observe the following good
practices:
1. When filling reservoir with hydraulic fluid, clean
area around filler cap before removing. Always filter
hydraulic fluid using a 10-15 micron filter before
adding to powerig.
2. Use clean funnel with filter.
3. Do not let hose fittings or couplings lie, or drag on
floor.
4. Wipe off couplings before connecting them.
5. Periodically, drain and clean reservoir and fill with
clean fluid.
REGULAR USE
Before using Hydraulic Unit:
1. Check hydraulic fluid level in reservoir and add fluid
as required.
2. Inspect hoses for damage and replace as required.
3. Check entire system for leaks and repair as needed

LUBRICATION OF THE AIR-DRIVEN MOTOR
If the pump is operated on a continuous duty cycle
or at maximum speed for an exteded period, an
automatic air line oiler is recommended. Install the
oiler in the air inlet line as close to the pumping unit
as possible. Adjust the oiler to feed 1-3 drops of
SAE #10 oil per minute (one drop for every 50-75
CFM of air) into the system.
HYDRAULIC FLUID LEVEL
Check the oil level in the reservoir after each 10
hours of use. Proper oil level is to top of sight
glass.
ADDING OIL TO THE RESERVOIR
Use only recommended hydraulic fluid. Disconnect
power supply when adding oil to the reservoir.
Clean the entire area around the filler plug before
removing the filler plug. Use a clean funnel with fil-
ter when adding oil.
MAINTENANCE CLEANING
Keep the outer surface of the pump, all hose con-
nections and any equipment hooked up to the
pump as free of dirt and oil as possible. The
breather hole in the filler cap must be kept clean
and unobstructed at all times. All unused couplers
are to be sealed with thread protectors. Change oil
as recommended.
