4.3 Air Supply Connections
Pump requires 60-100 psi dynamic air pressure at 20-100
cfm. A RFL-102 Regulator-Filter-Lubricator should be installed
upstream from the air inlet to provide clean, lubricated air, and to
allow for air pressure adjustment. Attach incoming air supply to
the 1/2" NPT port on the air valve.
4.4 Fluid Level
Check the oil level of the pump prior to start-up, if necessary add
oil by removing the SAE #10 plug from the cover plate (see Fig.
2). The reservoir is full when the oil level reaches the top of the
sight glass. (Fig. 4).
Tank is full
when oil level
is here.
4 and 8 liter
IMPORTANT: Add oil only when all system components are fully
retracted, or the system will contain more oil than the reservoir
can hold.

Thread hose(s) into outlet port(s) of the valve (see valve body for
port identifi cation).
Extend hose to valve port "A"
Retract hose to valve port "B" (if applicable).
Gauge to valve port "GA, GB, or GP".
("GA" measures "A" port pressure, "GB" measures "B" port
pressure, "GP measures pump pressure down stream of system
check).
5.0 OPERATION
1. Check the oil level of pump and add oil if necessary.
2. Make sure the shipping plug has been removed and the
breather cap is installed. (See section 4.1)

3. Place manual control valve in the Neutral position.
4. Connect unit to air supply
5. To start the air motor, slide the air valve inward.
6. To stop the air motor, slide the valve outward.

5.2 Relief Valve Adjustment
Z-Class pumps are equipped with one user adjustable relief valve
(see Figure 8.) It can be adjusted as follows:
1. Install a gauge on the pump.
2. Start the pump to allow the oil to warm.
3. Loosen the set screw locking nut.

Apply 1-1⁄2 wraps of Tefl on tape
or other suitable sealant to the
hydraulic hose fi tting, leaving the
fi rst complete thread free of tape
or sealant as shown in Figure 5.
