INSTALLATION INSTRUCTIONS (CONTINUED)
Installing Air Inlet Filter
Screw supplied air inlet filter into inlet port of cast iron
pump as indicated in Figure 6.
Lubrication
This unit contains no oil.
Before operating compressor, fill to the
center of the sight gauge (see Figure 6).
Using any other type of oil may
shorten pump life and damage valves.
Recommended Oil (2 Options)
Single viscosity SAE 30 ISO100 nondetergent compressor oil.
Part number ST125303AV (0.5 qt) or ST126701AV (4 qt).
10W30 synthetic oil such as Mobil 1
®
or CE0032 (1 qt).
Oil Capacity
Approximately 8.5 oz.
Fill the pump with oil to the center of the sight gauge
using oil fill opening (see Figure 6).
Do NOT fill the pump
through the breather cap opening as this may cause oil to leak
and spray out during operation.
NOTE:
Some residual oil may still be in the pump from
factory testing leaving a thin coat on the sight gauge;
however, there is not enough oil to operate the unit.
OPERATING INSTRUCTIONS
Important:
Check motor rotation before operating the
compressor.
All lubricated compressor pumps discharge some
condensed water and oil with the compressed air. Install
appropriate water/oil removal equipment and controls as
necessary for the intended application.
Failure to install appropriate
water/oil removal equipment may result
in damage to machinery or workpiece.
Guarding
The belt guard provided must be
installed before operating the unit.
All moving parts must be guarded. All electrical covers must
be installed before turning on the power.
