5. raise the nose until it meets the load contact
point.
6. pull the jack handle down firmly and evenly
until the top climbing pins snaps into the hole
on the jack bar, then raise the jack handle
until the bottom climbing pin snaps into the
next hole.
7. repeat Step 6 until you have raised the load
to your satisfaction, then raise and clip the
jack handle to the jack bar.
If the jack binds, support the load with a
jack or jack stands of equal or greater load
capacity, then remove the Model G8720 jack
and refer to
Page 3
for maintenance instruc-
tions.
Lowering a Load
1. Make sure the jack handle is in the upright
position and clipped to the jack bar.
2. push the direction latch down to disengage it
from the notch on the direction switch.
3. lower the handle until the bottom climbing
pin engages a hole in the jack bar, then raise
the handle until the top climbing pin engages
the next hole.
4. repeat Step 3 until the load is completely
lowered and the jack can be removed.
The jack must be supporting a load of at
least 110 lbs. before the lowering procedure
can be performed. Otherwise, the lifting
nose and assembly could suddenly drop
the load to the ground which could result
in serious personal injury or property dam-
age.
Like all machinery there is potential danger
when operating this jack. Accidents are
frequently caused by lack of familiarity or
failure to pay attention. Use this jack with
respect and caution to decrease the risk of
operator injury. If normal safety precautions
are overlooked or ignored, serious personal
injury may occur.
