Operation (Continued)
4. After all securing bolts are properly
fastened, open the release valve by
turning release knob counter-clockwise
to lower the jack to minimum height.
Avoid shock loads
created by quickly
opening and closing the release valve as
the load is being lowered. Shock loads can
create dangerously high operating
pressures within the hydraulic system,
causing system failure and resulting in
personal injury and/or property damage.
Maintenance
Use only a good
grade hydraulic jack
oil. Avoid mixing types of oil. Do not use
break fluid, alcohol, glycerin, motor oil etc..
Improper fluid can cause serious internal
injury to the jack, rendering it inoperative.
ADDING OIl
1. Position the jack on level ground with
saddle fully lowered, remove oil filler
screw.
2. Oil level should be within
3
/
8
” of filler
hole. DO NOT OVERFILL. If overfilled,
the jack will not lower to published
minimum height. If underfilled, the jack
will not reach published maximum
height. Adjust fluid level as needed.
Always reinstall oil filler screw before
use.
CHANGING OIl
1. For best performance and long unit,
replace the complete oil supply at least
once a year.
2. To drain the oil, remove the filler screw.
3. Lay the jack on its side and allow the oil
to run out into suitable drain pan.
Dispose of in accordance with local
regulations.
4. BE CAREFUL to prevent dirt or foreign
matter from entering the system.
5. Refill with proper oil (we recommend
Mobil DTE 13M or equivalent) as
described above.
NOTE:
Dispose of hydraulic fluid in
accordance with local regulations.
lubRICATION
Add lubricating oil to all pivoting sections
every 3 months.
PREVENTING RuST
1. Check ram and piston periodically for
signs of corrosion. Clean as needed
with an oily cloth.
2. When not in use, store jack with saddle
and piston fully retracted.
