SETUP
1. Remove the plug fittings in the air and hydraulic access holes. The threaded air inlet hole is at the end of the pump where the word
"pump" is on the foot pedal. The threaded hydraulic hole is at the opposite end of the pump. Remove any remnants of teflon tape or thread
sealer from the holes before installing hoses or air disconnect fittings.

AIR/HYDRAULIC FOOT PUMP
1. Determinethelayoutofyourhydraulicsystembasedonthework
to be performed. If the pump is used with a ram in collision repair
 workorinapressasapowersource,therewillmostlikelynotbe
a need to consider installing a flow control valve. If the pump
is used with a ram that activates a shop crane boom or any other
mechanical leverage that would increase the rate of descent of
such leverage when the pump pedal is released, install a flow
control valve between the pump and the ram.
IMPORTANT: Before using the pump under load, become
familiar with the operating of the foot pump. Depressing the foot
 pedalendmarked"pump"activatestheram.Toactivatetherama
small distance, it is necessary to use incremental taps of your foot
on the foot pedal until the ram reaches the desired distance.
Retracting the ram is accomplished by depressing the foot pedal
 endmarked"RELEASE".Thepumpisequippedwithatwospeed
 releasemechanism.Gentlydepressingthefootpedalendmarked
"RELEASE" retracts the ram slower then if you depress the pedal
all the way down. If you want to retract the ram slower than the
low speed release, use gentle incremental taps of your foot on the
"RELEASE" pedal.

3. Hose should not be twisted or bent too sharply. The bend radius
should not be less than nine times the outside diameter of the
hose. Always use as few bends as possible.
