4.5 Lift & Hydraulic Systems
4.5.1 Hydraulic fluid
The Quikstak hydraulic system is designed to operate using HM46 mineral-based hydraulic
fluid , with physical lubricating and chemical properties specified by ISO6743-4. The hydraulic
fluid should be topped-up quarterly and replaced annually.
4.5.1.1 Adding hydraulic fluid
Observe the following procedure
to top up the hydraulic fluid.
1. Prepare the Quikstak for
service and remove the
fascia cover as per
§4.3 .
2. Unscrew and remove the
filler cap from the hydraulic
reservoir, as per Figure 14.
3. Use a funnel to carefully
pour new hydraulic fluid
into the reservoir until the fill
marking shows between
four and five litres .
4. Replace the filler cap and
fascia cover.
Ensure the forks are completely lowered before replacing the hydraulic fluid.
Do not mix hydraulic fluids of different grades.
Do not add used or impure hydraulic fluid.
Do not fill the reservoir beyond the maximum fill marking (5 litres).
Always store and handle hydraulic fluids in accordance with the manufacturer’s
recommendations and all applicable regulations.
4.5.2 Powerpack
The hydraulic powerpack can be supplied as a complete unit, with the motor, pump, oil
tank, and control valves all mounted into a central manifold.
4.5.3 Lift motor
The hydraulic pump is driven by a 24VDC 2.2kW lift motor which generates 9.0Nm of torque
at 2300rpm, drawing up to 140 Amps of current. A motor solenoid (starter relay) is used to limit
the current draw when the motor is started.
4.5.4 Control valves
The hydraulic system has four primary control valves as described below, all of which are
mounted into the central manifold.
4.5.4.1 Check valve
This is a one-way valve which prevents oil from leaking back through the hydraulic pump
when the motor is stopped.
