NOTE: The speed of lowering is controlled by the Release Foot Pedal (10). It
is advisable to operate this pedal slowly in a controlled and safe manner
whenever lowering the Lift and its contents.
7) When the Lift is lowered, open the vise jaws, and remove the motorcycle
from the lift.
WARNING: The use of this lift is limited to the raising, lowering, and trans-
portation in the lowest position, of motorcycles. It is not designed to store
motorcycles or other parts. No motorcycle or other part should be left on the lift
for an extended period of time.
Do not overload. The capacity of this lift is 1/2 Ton (1000 Lbs.). This lift is de-
signed to use only on hard, level surfaces capable of supporting the load, the 350
lb. weight of the Lift and all supporting tools. Overloading or use on other surfaces
may cause instability and possible property damage or personal injury.
Maintenance
1) The hydraulic system is closed and will normally require no maintenance.
2) The mechanical parts of the Lift, such as the pedal lift and release shafts
should be occasionally lubricated with heavy oil or grease.
3) Protect the Lift Cylinder from dirt or grit, when in the raised position. If it
becomes dirty, wipe it off with a clean cloth.
4) Maintain and store the Lift in a reasonably protected environment. Do not
expose to rain or excess moisture. Protect from salt water or other corrosive
materials. If it becomes dirty or contaminated, clean it promptly with clean
water or a suitable detergent. If using a pressure washer, be aware that you
may remove some paint from the outer surface. Never apply a pressure
washer to the seal areas near the pistons or valves. Be sure to lubricate
external moving parts after cleaning.
5) If the lift “fades”, allowing a load to slowly lower on its own, you may have
damaged seals or insufficient lift oil. First check the oil level. If the level
is OK, take the lift to a qualified service technician for seal replacement.
Damaged seals may be caused by overloading, or exposure to harmful
conditions or inappropriate use of a pressure washer. NOTE: If the lift can
be pumped up to its highest position, it indicates that there is enough oil. If
the lift fades from this position, it indicates that the problem is likely with the
seals.
6) To check the oil level, be sure the lift is in its lowest position. Remove the
Oil Filler Plug (P22). The oil level should be even with the bottom of the filler
plug hole. You can visually see the oil, or test with your finger. If the oil level is
low, add any good hydraulic oil of 15/40 viscosity. Do not use any other oil or
brake fluid, which will damage the seals.
