•
Install air regulator
in the air-line and
set the pressure to
20–40 psi
(
1.4–2.8
BAR
) .
• Add an approved
hydraulic fluid to the
fill point of the Fill
and Bleed bottle .
To bleed and fill the tool:
1 .
Lay the tool on its side with the fill port facing up,
and remove the bleed plug (55) from the fill port.
2 .
Connect the tool to shop air-line. If fluid is present,
hold the tool over a suitable container with fill port
facing into container . Cycle the tool several times to
drain old fluid, air, and foam. (Figure 10)
3 .
Screw the fill bottle into the fill port.
4 . Stand the tool upright on a bench . Trigger the tool
slowly (20–30 cycles), and bend the fill bottle at a
right-angle to the tool . (Figure 11)
When air bubbles stop accumulating at top of the
bottle, stop cycling the tool . When the trigger is
released, the pull piston returns to the idle position
(full-forward) .
5 .
Disconnect the tool from the air-line.
6 .
Lay the tool on its side and remove the fill bottle.
Top off the fluid in the fill port, and install and tighten
the bleed plug .
7 . Connect the air-line to the tool and measure the
stroke as described in
M
easurIng
t
ool
s
troke
on
page 15
. If the stroke is less than specified,
remove the bleed plug and add fluid. Re-insert the
bleed plug and recheck the stroke .
8 .
Increase the air pressure to specifications. Install
two fasteners to check the function and installation
in a single stroke, or cycle the tool with a stall nut
fully threaded onto the piston to load up the tool .
Measure the stroke again . Remove the plug and
add fluid. Re-insert the plug and cycle and measure
again . Repeat this process until the stroke meets the
minimum requirements .
WARNING: Avoid contact with hydraulic
fluid. Hydraulic fluid must be disposed of
in accordance with local regulations. See
MSDS for hydraulic fluid shipped with tool.
Figure 9
WARNING: Air pressure must be set at
20–40 psi (1.4–2.8 BAR) to prevent possible
injury from high-pressure spray.
If the bleed plug (55) is removed, the Fill and
Bleed bottle must be in place before cycling
the tool.
Figure 10
CAUTION
: All fluid must be purged from the
tool before refilling. The tool stroke will be
diminished if the fluid is aerated.
For optimal performance, refill with a fluid
that is recommended in
s
PecIfIcatIons
.
