6. Startup Procedure
 Double check all electrical & hydraulic
connections
 Run power unit momentarily ensuring the
pump is priming & the load has started to
move.
 If load doesn’t move after a few tries
reference troubleshooting section –
pump not priming
 Check voltage drop
 Connect a volt meter to the power
unit not the battery.
 Run power unit momentarily the
voltage should not drop below 11.4
volts with a full charged battery.
 With a fully charged battery the
maximum voltage drop is 5%
 Purging air from hydraulic system
 Start by cycling the cylinder about
25% of the full stroke of the cylinder.
 During and after each stroke keep an
eye on the fluid level and condition of
the fluid in the reservoir.
 The fluid level should never exceed
2’’ from the bottom of the reservoir
 Check for excessive aeration of the
hydraulic fluid. Increase time
between cycles if fluid aeration is
present.
 If excessive aeration persists stop
cycling the cylinder, let the unit rest until
the air has dissipated from the reservoir
then continue cycling.
 To reduce the amount of air being
reintroducing to the hydraulic system
 Let power unit rest between cycles,
 With each cycle of the cylinder
increase the stroke by 25% or less
 You may need to add fluid to the
reservoir after each cycle.
 Only add fluid when cylinder is
retracted
 For intermittent duty applications the
reservoir volume is sized off the rod
volume of the cylinder, plus a
percentage to prevent pump
cavitation. More down time between
cycles will be required when
bleeding the system
 Always check battery voltage before
 Double check hydraulic system
 Check all fitting and hoses for leaks
 If you think you may have one wipe
the fluid off & cycle the unit a few
times ensuring the fluid is not some
residual fluid residue from installation
 Check all electrical connections
making sure they are tight
 Check fluid level
 Check charging system ensuring the
battery is able to receive a charge
