OPERATION (con’t)
NOTICE:
operate pump handle at slower speed during the high
flow 1st stage to ensure the pump delivers maximum oil volume.
MAINTENANCE
1. Inspect hoses and connections daily. Replace damaged
components immediately with Williamss Replacement Parts
only.
2. Tighten connections as needed. Use pipe thread sealing
compound when servicing connections.
3. Use only good quality hydraulic fluid. We recommend using
premium hydraulic fluid.
Never
use brake fluid, transmission
fluid, turbine oil, motor oil, alcohol, glycerine etc. Use of other
than good quality hydraulic oil will void warranty and damage
the pump, hose, and application.
Adding Hydraulic Fluid
1. Depressurize and disconnect hydraulic hose from application.
2. With pump in its upright, horizontal position, remove vented oil
filler plug/screw located on top of the reservoir.
3. Use a small funnel to fill reservoir to within 1/4ʺ (6 mm) of the
opening.
4. Wipe up any spilled fluid and reinstall the vented oil filler plug/
screw.
5
Changing Hydraulic Fluid
For best results, change fluid once a year.
1. Remove vented oil filler plug/screw and drain used fluid into a
sealable container.
2. Dispose of fluid in accordance with local regulations.
3. Fill with a good quality hydraulic jack oil as recommended above.
Reinstall vented oil filler plug/screw.
Lubrication
Use a light machine oil to lubricate pivot points, hinges etc.
Storage
1. When not in use, depressurize and disconnect hoses from
application.
2. Wipe clean, throughly
3. Pump should be stored where protected from the elements,
abrasive dust, and damage. Store in clean, dry environment.
Avoid temperature extremes. Lock handle into position using
the spring loaded locking pin mechanism.
4. Shield pump with a protective cover.
TROUBLESHOOTING GUIDE

Symptom
Possible Causes
Corrective Action
Erratic application action
• Air in the system.
• External leak.
• Internal hydraulic leak.
• Vent the system.
• Tighten all connections.
• Contact service center.
Application does not extend, move
or respond to pressurized fluid
• Overload condition.
• Release valve not closed.
• Loose couplers/connections.
• Faulty couplers/connections.
• Pump malfunction.
• Remedy overload condition.
• Ensure release valve closed.
• Tighten couplers/connections.
• Replace couplers/connections.
• Contact service center.
Application responds to pressurized
fluid, but system does not maintain
pressure
• Overload condition.
• Release valve not closed.
• Pump or valve malfunction.
• Application/connection leaking.
• Remedy overload condition.
• Ensure release valve closed.
• Contact Service Center.
• Replace application/connection.
Application responds slower than
normal
• Loose connection or coupler.
• Restricted hydraulic line or fitting.
• Application/connection leaking.
• Tighten connection or coupler.
• Clean and replace if damaged.
• Replace application/connection.
Application does not return fluid to
pump (i.e. cylinder will not retract)
• Malfunctioning coupler, damaged
application.
• Reservoir overfilled
• Secure load by other means. Open release
valve, depressurize pump and hose,
remove coupler and/or application, then
renew or replace.
• Secure load by other means. Open release
valve, depressurize pump and hose,
remove application, then drain fluid to
proper level.
Poor performance
• Fluid level in pump is low.
• Ensure proper fluid level.
