Equipment Required:
- Shop airline with 90 - 100 psi max.
- Air regulator
- Fill bottle, 120337, (supplied with tool).
- Large fl at blade screwdriver
- Optional Stall Nut 124090 or 125340
- Nose assembly
- Fasteners (optional)
Preparation:
• Install air
regulator in airline
and set pressure
to 20-40 psi.
• Fill bleed bottle
almost full of
DEXRON III ATF
or equivalent.
Step 1
With fi ll port facing up, lay tool on it’s side, and remove
bleed plug (55) from bleed port.
Step 2
Connect tool to shop air set at 20 to 40 psi. If fl uid is
present, hold tool over suitable container with fi ll port
facing into container. Cycle tool several times to drain
the old fl uid, air and foam (Fig. 10)
Step 3
Screw fi ll bottle (120337) into fi llport.
Step 4
Stand tool upright on bench. While triggering tool
slowly (20 - 30 cycles), bend fi ll bottle at right angles
to tool (Fig. 11) . Air bubbles will accumulate at
top of the bottle. When bubbles stop, cycling may be
discontinued.
Step 5
When trigger is released, pull piston returns to idle
position (full forward). Disconnect tool from airline.
Step 6
Lay tool on it’s side and remove fi ll bottle. Top off fl uid
in fi ll port, install bleed plug and tighten.
Step 7
Connect airline to tool and measure the tools stroke,
refer to the Measuring Tool Stroke section. If stroke
is less than specifi ed, remove bleed plug and top off
fl uid. Reinstall bleed plug and recheck stroke.
Step 8
Increase air pressure to specifi cations. Install two
fasteners to check function and installation in a single
stroke, or cycle tool with stall nut fully threaded onto
piston to load up tool. Measure stroke again. Remove
plug and top off fl uid. Reinstall plug and cycle and
measure again. Continue this process until stroke
meets minimum requirements.

CAUTION: Refi ll using Automatic
Transmission Fluid DEXRON III or
equivalent for optimal performance.
WARNING: Avoid contact with hydraulic
fl uid. Hydraulic fl uid must be disposed
of in accordance with Federal, State and
Local Regulations. Please see MSDS for
Hydraulic fl uid shipped with tool.
WARNING: WARNING: Air pressure
MUST be set to 20 to 40 psi to prevent
possible injury from high pressure
spray. If plug (55) is removed, fi ll bottle
must be in place before cycling tool.
CAUTION: All oil must be purged from
tool before Fill & Bleed process. Tool
stroke will be diminished if oil is aerated.
