6.4 Control Valve
The control valve is 3-way, 2-position lever operated device.
To advance the cylinder, move the valve handle away from the
pump (fully clockwise). Then, apply pressure to the trigger as
required to start the motor and achieve the desired speed. The
cylinder will continue to advance until the trigger is released or
the cylinder reaches its maximum travel.
IMPORTANT: Support the load with suitable blocking and
cribbing after extending the cylinder the desired amount. The
pump control valve does not provide a pressure or load holding
feature.
To retract the cylinder, move the valve handle toward the pump.
Hydraulic pressure will immediately be released from the cylinder,
allowing it to retract.
IMPORTANT: When the handle is moved to the retract position,
the cylinder will retract with or without the pump running.

6.5 Air Removal
When the hydraulic system is connected for the fi rst time, air will
be trapped in the components. To ensure smooth, safe operation,
remove the air by running the system through several complete
cycles. Do this with no load on the cylinder, and with the pump
reservoir positioned
higher than the cylinder. When cylinder
advances and retracts without hesitation, the air is vented from
the system.
7.0 BATTERY PACKS
7.1 Installation and Removal
• To install battery pack on pump: Slide the pack down onto the
powerhead. Make sure it latches securely into place.
• To remove battery pack from pump: Push in the release buttons.
Pull the battery pack up and remove it from the powerhead.
Two 28 volt Li-Ion battery packs and one battery charger are
provided with each pump. If needed, additional battery packs
and chargers may be purchased from a Milwaukee Electric Tool
retailer. To ensure compatibility and proper operation, use only
MILWAUKEE battery packs and chargers. Be sure any additional
battery packs or chargers are the same model number as those
originally supplied with the pump.
New battery packs must be charged before use. For specifi c
charging instructions, and additional battery pack information,
refer to the separate battery and charger instruction sheet
included with the pump.

7.2 Fuel Gauge
Each battery pack contains a “fuel gauge”. The indicator lights
show the approximate run time remaining before the battery
becomes completely discharged.
Press the fuel gauge button to display the lights. The fuel gauge
will stay lit for two seconds.
IMPORTANT: Run time percentages shown in Figure 9 are
approximate. Run time between battery charges is dependent
on the application, pump run time, pressure setting and other
factors.
Note: Run time is less than 10% if bottom light is fl ashing.
Figure 9, Fuel Gauge
Note: If the fuel gauge doesn't appear to be working, place the
battery pack on the charger and charge as needed.
7.3 Cold Weather Operation
The V28 ™ Lithium-Ion battery pack can be used in temperatures
down to -4ºF [-15ºC]. When the battery pack is very cold, it may
pulse for the fi rst minute of use to warm itself up. Put the battery
pack on the pump and operate the pump under a light load.
After about a minute, the pack will have warmed itself up and will
operate normally. If the battery pack is used too hard before it
has warmed up, it may “buzz” for 5 seconds and then turn itself
OFF.
