2.
Unscrew the head assembly P-606 and take it out of the tool.
The long arm of a Allen wrench may be inserted into one of
hole at the base of head P-606 to help unlock the assembly.
3.
Pull-out the piston assembly and unscrew the cylinder P-618.
Perform a visual inspection of the driving blade P-423, the
wear-ring P-622A and the inner surface of the cylinder P-618.
Do not remove the driving blade from the piston.
4.
Pull-out the valve assembly P-643 and perform a visual
inspection of all rings. Check that the actuator assembly
P-642/P-644 is sliding easily on valve P-643. Clean and
lubricate lightly. It is usually not necessary to take apart the
actuator assembly.
5.
If necessary, actuator cap P-644 may be unsnaped from
actuator P-642 by inserting the long arm of an Allen wrench
through the hole on top of the actuator and using a hammer
with moderate force to get the parts apart.
6.
Clean the inside wall of the head body P-606 and lubricate
lightly with a non-detergent oil. Check the o-ring P-606A. It is
generally not necessary to remove the head cap P-601.
REPLACING THE DRIVING BLADE
The driving blade is sold separately or supplied as a complete
subassembly with the piston P-622.
1.
Unscrew the head assembly P-606 and take it out of the tool.
2.
Pull-out the piston assembly from the cylinder. Remove any
debris and assess condition of cylinder P-618. If marked or
grouged, use a fine sand paper to smooth out walls. The
piston P-622 must be allowed to move without restriction.
Skip to step (7) if you are replacing with a piston/driving blade
subassembly.
3.
Lock the piston in a vise, using
a rag to prevent scoring.
Always use the top and bottom
faces to secure the piston in
place.
4.
Remove the broken driver
using a 1/2" close wrench.
5.
Put one drop of medium
strength adhesive sealant onto the threads of the piston
P-622.
6.
Insert the P-622C lock washer and screw the new driving
blade onto the piston P-622. Tighten very hard (140 lb
in
minimum). Make sure that the lock washer P-622C is
completely flattened.
Note: select the appropriate driving blade:
• use P-423 driving blade for the "L" or "T" bailers
• use P-237 driving blade for stapler configuration
7.
Insert the piston sub-assembly into the main body P-616 and
engage the driving blade P-423 in the seal bushing opening.
Depress the safety contact P-562 to ensure that the driving
blade has engaged the gate/foot assembly guiding channel.
8.
Tighten the cylinder P-618 onto the head P-606 and follow the
procedure to complete the assembly of the head.
INSTALLING THE SAFETY
You shouldn't need to remove the safety stop mechanism unless
the element P-561 do not swivel or has a broken tip.
1.
Assemble together parts P-561, Q-061A , Q-061C and
Q-061D.
2.
Insert the short end of P-561B as shown.
3.
Put two drops of adhesive sealant onto the thread area of
Q-061C, near its cylindrical end. Make sure no sealant is
retained on the end or exterior wall.
4.
Insert the assembly into the hole in the tool body as shown.
5.
Tight together with screw P-153A, holding Q-061C.
INSTALLING THE BASE ASSEMBLY
The plastic base can be installed or removed without the need of
a tool.
1.
First, insert connecting stem
P-561B to the safety contact P-562.
2.
Lift the safety contact and fully
slide-in the plastic base P-533 onto
the brackets P-535A & B.
3.
The safety contact should simply
drop into place. Insert the locking
rod P-562 until it snaps. It should
engage the safety contact.
