Maintenance Hints & Tips for the WK10HD Air Tool
Ensure that the mesh filter located in the end of the air line is clean and also that an adequate volume of
appropriate air pressure is delivered to the air tool motor.
Check that the blade set screw
(SPB33)
is not protruding from the chuck, as this will cause the reciprocating chuck
to jam against the guide head
(SPB6)
.
Ensure that the trigger/lever
(SPB30)
is depressing the air valve
(SPB18)
.
Again, the chuck may jam if longer
SPB32
screws are fitted to the controller cap
(SPB34K)
.
Similar to a car engine, this precision tool must be regularly lubricated with the recommended oil.
While depressing the trigger/lever
(SPB30)
to maximum, bump or jar the air tool at the chuck end several times.
Often this action will dislodge an obstruction and will re-start the tool.
FURTHER ADVICE
Remove the two cap screws
(SPB32)
and remove the controller cap
(SPB34K)
from the air tool.
When the air is disconnected, use your finger to apply pressure to the chuck
(SPB7K)
to check if the chuck is freely
reciprocating without any obstruction inside the guide head
(SPB6)
.
If necessary, remove the four
SPB36
front screws from the
SPB6
head. The piston assembly can now be removed
from air tool body. The piston assembly should now freely slide in and out of air tool body/cylinder.
Be aware that the rear spring
(SPB11)
and the washer
(SPB43)
are located behind the piston assembly.
Also check that the piston
(SPB4)
slides backward and forward on the piston rod
(SPB3)
.
If burrs or scratches are found on the surface of the cylinder, piston or piston rod, these should be removed with a
light grade emery paper.
The piston assembly and other components should be cleaned thoroughly, pre-oiled and re-fitted to the air tool body.
When replacing the piston assembly into the air tool, it is important to correctly align the guide head
(SPB6)
with
the chuck
(SPB7K)
. With
SPB36
screws slightly loose, connect air line and while holding air tool vertical with the
chuck at the top, operate the air tool at the same time as the
SPB36
screws are alternatively tightened.
Once again, while the air is disconnected, use your finger to apply pressure to the chuck
(SPB7K)
to check if the
chuck is now freely reciprocating without any obstruction inside the guide head
(SPB6)
.
Replace the Controller Cap (
SPB34K
) and re-tighten the two cap screws (
SPB32
).
IF THE BLADE COMES LOOSE
It is important that the correct
SPB33
Cone Point Set Screw is used in the chuck to lock the blade tight in the
chuck. Do not use the Flat ended Set Screw
(SPB33F)
for blade fixing. The
SPB33F
set screw is
only
for retaining
the air hacksaw blade when using the air tool as an air hacksaw.
IF PROBLEMS STILL EXIST, SEND YOUR BTB AIR TOOL TO A PROFESSIONAL BTB REGISTERED SERVICE AGENT.
FLUSHING OUT THE AIR TOOL MOTOR
Do not use thick or unspecified oil or allow compressed air to deliver water or other foreign bodies into the air
tool motor. The tool may stop if the lubrication becomes contaminated and sticky, or if a small particle of
debris temporarily jams the piston. If point
6
above does not re-start the tool, refer to the following:
Flush out the air tool motor by adding a small quantity of appropriate flushing agent via the oiling point.
IMPORTANT:
With the air tool exhaust pointed in a direction away from the operator, depress the lever
(SPB30)
and operate the tool until the flushing agent is discharged through the exhaust.
NOTE:
To avoid the discharge being absorbed into the muffler foam
(SPB38)
, remove muffler clip
(SPB25)
,
then using masking/electrical tape, seal the end of the muffler sleeve
(SPB24)
to the air line
(SPB28A/L)
.

Air tools provide optimum performance with a clean air supply and proper lubrication.
If your air tool develops a lack of power or fails to start when you depress the trigger:
