5.6 Air Requirements
CAUTION Before connecting the air supply hose,
ensure that the air on-off control is in the OFF position.
Failure to follow these directions may result in unintended
pump startup when air supply hose is connected.
To ensure optimum performance, the air source must be
capable of providing a constant supply of air at the required
pressure and fl ow rate for your pump model. Refer to Table 4.1
for additional information.
NOTICE
Supply air pressure should not exceed 110 psi [7.5
bar] static for MAP30 Series models. Supply air pressure
should not exceed 120 psi [8.2 bar] static for MAP07 and
MAP15 Series models.
Figure 7 - Pump Air Inlet
Air coupler
(user-supplied)
Air Inlet
1/4" NPT
Use only dry and fi ltered compressed air. Use of a water separator
is strongly recommended. Pump internal components are self-
lubricating. Lubricated air is permitted but NOT required.
The pump air inlet connection is a 1/4" NPT fi tting. See Figure 7.
A suitable male air coupler (user supplied) must be installed
between the pump air inlet connection and the air supply line
or hose. Use PTFE sealing tape (or other suitable pipe sealant)
on the threads and torque to 7.4-11.0 ft-lb [10-15 Nm].
To ensure suffi
cient air fl ow, the inside diameter of the air
supply hose or line must be not less than 0.39 inch [10 mm].

5.4 Oil Level
The oil level sight gauge is located on the left-hand side of the
pump,
The reservoir should be 1/2 to 3/4 full with all cylinders or other
hydraulic actuators fully retracted. See Figure 5.
Never allow the oil level to rise above the top (high) line or fall
below the bottom (low) line.
NOTICE
Always check oil level with the air on-off control in the
OFF position and the hydraulic system fully depressurized. Be
certain that all hydraulic actuators are fully retracted. Failure to
observe this instruction may result in the reservoir becoming
overfi lled.
Figure 5 - Oil Level Sight Gauge
Oil Level
Add oil if the oil level drops below 1/2 full. A small amount of
additional oil may need to be added to the reservoir after the
pump has been operated for the fi rst time.
5.5 Hydraulic Hose Connections
The advance and retract ports are located on the front of the
hydraulic manifold. See Figure 6. Note that the top ports are
labeled “B” and the bottom ports are labeled “A”.
Port type and thread size will vary, depending on pump model.
Refer to Section 4.2 of this manual for additional information.
All hoses, fi ttings and other hydraulic components in the circuit
must be rated at or above the pump maximum working pressure.
Refer to sections 4.1 and 6.2 of this manual for additional
maximum pressure information.
