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.
