MAINTENANCE (continued)
Adding Hydraulic Fluid
1. Depressurize and disconnect hydraulic hose from application.
2a. For Model B65425 and B65427:
With pump in it's upright, horizontal position, remove the air vent plug located on the top plate of the reservoir.
2b. For Model B65426:
With pump in it's vertical position, remove the reservoir cap located on the reservoir.
3. Use a small funnel to fill reservoir to within 3/4" (19mm) of the opening.
Note: Use only a good quality hydraulic jack fluid. Never use brake fluid, transmission fluid, turbine oil, motor oil,
alcohol, glycerin etc. Use of other than good quality hydraulic oil will void warranty and damage the pump, hose,
and application.
4. Wipe up any spilled fluid
5. Reinstall the air vent plug.
Changing Hydraulic Fluid
For best performance and longest life, replace the complete fluid supply at least once per year.
1. Depressurize and disconnect hydraulic hose from application.
2. Repeat #2 above, then pour used fluid into a sealable container.
4. Use a small funnel to fill reservoir to within 3/4" (19mm) of the opening.
5. Dispose of fluid in accordance with local regulations.
6. Fill with a good quality hydraulic oil as recommended above.
7. Reinstall air vent plug.
Lubrication
Use a light machine oil to lubricate pivot points, hinges etc.
Note: Never operate pump with release valve closed and disconnected from application. If operated in this condition, the
hose and connections become pressurized. This increases burst hazard. Damage may occur to pump and its components
