4. Hints, Tips and Operating
Techniques
4.1 Standard Blades
(Including Serrated Blades)
1. Select a blade type and colour that allows the flat side of the
blade to hug the surface you want to cut the adhesive away
from.
2. When the flat side of a
YELLOW
or
GREEN
blade tip is against
glass it will always cut close to the glass surface.
3. When the flat side of an
ORANGE
'R' or
BLUE
'VR' (reverse)
blade tip is against the pinchweld it will always cut close to
the pinchweld, away from encapsulated mouldings, heater
elements or sensors.
4.
Standard
(non-serrated) blade tips cut adhesive with a
reciprocating (in and out) action with the tip of the blade
jabbing in and out of the adhesive bead, rather than a sawing
action.
5.
Serrated
blades should be operated at approximately 45
o
to
90° to the adhesive in a sideways or backward sawing motion.
Use caution when operating reverse (ORANGE) blades close to
headliners or trim panels and use headliner protection methods.
6. Do not force the blade deep into adhesive. It is more effective
for the power tool to operate continuously while progressively
steering the blade back and forth along a short section.
7. On difficult removals, always cut the easy-to-get-at areas first.
This will release pressure on the glass and provide easier access
to the difficult areas, resulting in a faster cut-out.
8. Do not use long blades when a short blade will do. A short blade
brings the blade cutting tip closer to the nylon controller cap,
resulting in faster and more precise cutting of the adhesive.
9. If a blade is not cutting efficiently, is flapping against the glass or
is making excessive noise, the tool and blade are being held at
an incorrect angle and/or the wrong blade is being used.
10. For efficient cutting and to avoid heat build up, ensure blades
are sharp. Also ensure the cutting area is regularly lubricated
with an appropriate cutting fluid, to both inside and outside
glass surfaces if possible.
11. To overcome the difficulties of cutting wire and small cutting
tips consistently catching on cracks in the uneven surface of a
damaged laminated glass, use Standard blades with their wide
and flat cutting tips to effectively cut against the surface.
12. When cutting from inside the vehicle, the nylon controller cap
should be held against the glass surface wherever possible. It
will not scratch the glass or painted panel and will steer the
blade tip to the correct cutting angle.
13. Use adjustable cutting depth controller arms to avoid causing
damage to the painted body panel, mouldings or blade. When
using Orange or Blue Reverse blades, always use a control arm
between the glass and blade See
Diagrams H, U
and
Diagram V
.
14. Adhesive Velcro® protection pads (included in BTB kits) can be
fitted to blades to protect the glass surface and painted panels.
15. Plastic locator pins, Velcro® pads or bolts are often used in
addition to adhesive when a glass is installed. Use a blade to
pre-cut plastic pins or Velcro®. When cutting around steel bolts
or pins, to avoid blade damage, mark the location of bolts/
pins with masking-tape, then carry out a normal cut out while
working as close as possible around the pin. Use blades in a
manual handle to finish around difficult areas.
16. To retain thumb on trigger of E-Tool when switching from
the left side to right side, refer to section
2.2.1.4 Cutting Below
Dashboard while Standing in Doorway (page 8)
.
5. Tool Repair & Part Replacement
For all other problems contact your nearest BTB Distributor or your
nearest Authorised BTB Repair Agent. Do not try to repair the tool
yourself. Opening the tool up will void your warranty.
For additional tools or replacement controller caps contact your
place of purchase.

4.2 Powered Cold Knife Blades
(WK27 and WK28 Blade range)
1. Do not force the Powered Cold Knife (PCK) blades. Align
the power tool and blade tip parallel to the glass. Allow the
reciprocal action to do the work. The recommended and
most effective method for using PCK blades with the E-Tool
is to push the blade in a forward motion. Where pushing is
not possible refer to section
2.2.10.1.h.
Always apply cutting
lubrication, ensuring the leading edge of blade tip is hugging
the glass surface. Refer to
Diagram Z
for WK27 and WK28 usage
instructions regarding correct angle of blades. If cutting wide
adhesive bands, always use the shortest cutting tip first, then a
longer version to complete the cut out.
2. To create a starting point for a PCK blade, a combination of
inside and outside cutting can be the most effective. e.g. From
inside, first cut a small section at a corner, which allows entry for
the PCK blade from outside. For windshield removal, the PCK
blade can also be operated in a pulling motion, allowing these
blades to be entered/started at the bottom of an 'A' pillar (below
the guard or bonnet) pulling in a backward direction (up the 'A'
pillar).
3. Performance will be reduced if the blades are not sharp or
spacing between the glass and pinchweld is minimal.
