Mountain MTN5505 Operating Instructions

Operating Instructions:
IMPORTANT: Sometimes during shipment and handing, air gets
into the hydraulic system, causing poor lifting performance. Before
initial operation, purge any air from the system by fully opening
release (Turn handle knob (#80) counter-clockwise). Then, while
holding the saddle down, pump pedal (#63) rapidly several times.
RAISING JACK:
1. Turn handle knob (#80) clockwise until resistance is felt to close
release valve. Do not over tighten.
2. Place jack directly under object to be lifted. Depress the pedal
(#63) repeatedly until the saddle contacts the lift point. Make
sure saddle lifts weight firmly and centrally. Check positioning
under slight load to confirm jack or load will not slip.
3. Raise jack by pumping handle until desired height is reached.
After lifting, secure load by appropriate means. Do NOT use
service jack as the only means of support.
LOWERING JACK
1. Slowly turn handle knob (#80) counter-clockwise. Speed of
descent is controlled by amount release valve is turned.
Maintenance:
Checking hydraulic oil level
1. Open release valve (turn handle knob (#80) counter-clockwise)
and push ram to its lowest position.
2. Remove filler plug (#36).
3. Fill the reservoir with clean hydraulic jack oil. Do not use
hydraulic brake oil or hydraulic brake fluid.
4. Reinstall filler plug.
Lubrication:
1. Add lubricating oil to all moving parts as needed.
