Maintenance
1.
Lubrication.
LACK OF OIL CAN CAUSE MALFUNCTION. Occasionally lubricate the handle socket pivot point,
extension screw, and release screw thread to prevent corrosion.
2.
To Add or Replace Hydraulic Jack Oil.
a)
Retract ram completely.
b)
Remove filler plug with your fingers and fill reservoir with designated jack oil or general hydraulic fluid to the
bottom edge of fill hole with jack upright.
c)
Replace filler plug, operate pump to the ram's full height, and continue pumping for five or six times at the position.
Push down ram completely and push open filler plug sideways to let out air.
Proper Oil:
ISO VG 10. Never use high viscosity oil or volatile oil such as brake oil or vegetable oil which may cause
malfunction. We recommend annual oil replacement and inspection. Please contact a
ZINKO
service center for service
inspection.
3.
Storing Jack.
After using, clean jack, check sliding and rotating parts and oil as needed. When storing, keep ram and
extension screw at lowest position and store the unit(s) indoors.
1.
DO NOT OVERFILL OIL BEYOND THE OIL FILL LEVEL, AS THE JACK'S OIL AMOUNT LIMITS THE MAXIMUM
EXTENSION OF THE RAM.
Too much oil may make the ram fall off, which may result in a serious accident.
2.
SLOWLY TURN RELEASE STEM.
Turning it quickly makes a heavy load fall rapidly, which may result in jack's
losing engagement at jacking point, and/or damage to jack leading to a serious accident.
3. If stains on labels make it difficult to make out the instructions on them, or jack appears to be in an abnormal
condition, consult your dealer immediately.
4. Ensure no foreign matter such as dirt enters the system while filling oil.
NEVER USE BRAKE OIL OR VEGETABLE
OIL, AS SUCH OIL CAUSES JACK TO MALFUNCTION.
