INTRODUCTION
This patented windshield tool is the original internal cut method, which
succesfully removes urethane set windshield glass including vehicles with
urethane set mouldings, encapsulated mouldings and/or where the
urethane adhesive is located away from the edge of the glass, or hidden far
below the dashboard area. The blade reciprocates against the surface of the
glass on the inside of the vehicle, quickly and efficiently cutting the
urethane adhesive around 100% of the glass perimeter. Force is eliminated
and urethane set mouldings remain installed.
GENERAL GUIDELINES AND REMOVAL INSTRUCTIONS
FITTING OF BLADES TO AIR TOOL
When installing blades into the air tool, always disconnect the air line. To fit
blade, using the 4.0mm hex key provided, unscrew the cone point retaining
screw in the blade chuck. Insert the blade as far as it will go into the chuck,
view through inspection hole and re-tighten retaining screw. Re-connect air
line ready for use.
ALL BLADES CAN ALSO BE FITTED IN THE MANUAL HANDLES
The same blade chuck is fitted into the WK7 and WK7L handles.
RANGE OF BLADES
A comprehensive range of blades are available to service the majority of
installations.
CONTROLLER CAP
The controller cap allows the depth controller arms to be attached and
adjusted and is designed to be held flat against the glass surface. This
guarantees the blade is also held flat and hugging the glass surface for
efficient cutting and operator control. (Refer Diagram
A
and
B
).
CORRECT CUTTING PROCEDURES
Diagram
C
shows the correct method to operate the air tool. The controller
cap and blade are flat against the glass and the operator's hand is placed
under the tool to allow the back of the air tool to also operate as close to the
glass as possible.
INCORRECT CUTTING PROCEDURES
Diagram D shows the air tool being used incorrectly. The blade is being
forced into an unnatural bent position and the hand is placed on top of the
air tool. This will cause blade vibration and "flapping", plus inefficient
cutting of the adhesive.
URETHANE SET MOULDING REMOVAL
When bonded mouldings are present, always carry out the normal internal
cut of glass, then apply one of the following steps:
1.

CUTTING PROCEDURE USING THE RECIPROCATING AIR POWER TOOL
Position the tool and blade against the glass. Start the tool and adjust
power. Depress the Speed trigger and hold on to maximum. Proceed to cut
the urethane adhesive as recommended below:
1.
2.
With harder type adhesives, especially on curved glass, it is recommended
that jabbing the air tool and blade quickly in and out of the urethane
adhesive and with a combination of adding lubrication is most effective,
especially where adhesives are hidden below dashboard areas.
EXTRA HARD AND/OR WIDE ADHESIVE
When cutting extra hard and/or wide adhesives, make sure blades are sharp
and cutting lubrication is applied. With the tool and blade operating in a
straight line, apply the tip of the blade directly at the adhesive and
combined with a quick jabbing action, move from left to right over a short
distance, progressively cutting through the adhesive. Ensure separation is
complete before moving on to next section. (Refer Diagram
B
and
E
).
Do not force blades deep into adhesive or unnecessary jamming may result.
Remember to depress speed/power trigger to maximum to allow the air
tool and blade cutting tip to OPERATE CONTINUOUSLY while cutting all
urethane adhesives.
On adhesives that are sometimes small and/or the softer type, hold the
tool and blade at 45° and apply some pressure to encourage and create
continuous cutting using the tip and side of the blade,
OR
Hold the tool and blade at 90° and use in a sawing motion while moving
from left to right.
Lift glass out with mouldings still attached to glass (Refer diagram
F
).
