2. INTRODUCTION
Twin piston Rocket Lift feature brings lifting arm straight into contact with the jacking point in 3-4 strokes. Universal joint release mechanism
allows safer, more controlled lowering of the jack. Profiled lifting arm gives low clearance height of just 90mm x 390mm deep, making this unit
suitable for sports and custom cars. Heavy-duty chassis with strengthening flanges along the side for extra torsional rigidity under load. Fitted
with heavy-duty one-piece hydraulic unit with pump-through action preventing handle locking at maximum ram extension. White saddle aids
positioning under vehicle and safety valve prevents overloading. Supplied with foam jacking handle sleeve to prevent damage to the vehicle’s
bodywork and integral saddle pad.

6. MAINTENANCE
IMPORTANT: Only fully qualified personnel should attempt maintenance or repair.
6.1. Monthly Maintenance.
6.1.1. Lubrication is critical to jacks, since they support heavy loads. Any restriction due to dirt or rust can cause either slow jack movement or
erratic movement, causing damage to the internal components. To keep the jack well lubricated, carry out the following steps.
6.1.2. Lubricate the ram, the linkages and the saddle and pump mechanism with light oil.
6.1.3. Grease the wheel bearings and axles.
6.1.4. Keep all jack surfaces and warning labels clean.
6.1.5. Check and maintain the ram oil level (Section 6.3).
6.2. Three Monthly Maintenance.
At three monthly intervals, check the ram for any signs of rust or corrosion. Clean the ram as required and wipe with an oiled cloth.
6.3. Checking the Oil Level.
6.3.1. Fully retract the ram by turning the release valve anticlockwise.
6.3.2. Undo the four top plate retaining screws and remove the top plate.
6.3.3. With the jack in the level position, remove the oil filler plug.
6.3.4. The oil should be level with the bottom of the oil filler hole. If it is not, top up with clean hydraulic jack oil (Sealey Part No: HJO500MLS
or HJO5LS).
6.3.5. Replace the oil filler plug and check the jack operation.
6.3.6. Purge any air from the hydraulic unit as required. Refer to Section 4.4.
6.3.7. Replace the top plate and secure with the four screws.
NOTE: Always store the jack in the fully lowered position. This will protect critical areas from excessive corrosion.
