1.2 Vibration Emission Levels
The vibration emission level of the tool has been measured in
accordance with a standardised test given in EN 60745 and may
be used to compare one tool with another. It may be used for a
preliminary assessment of exposure.
The declared vibration emission level represents the main
applications of the tool. However if the tool is used for different
applications, with different accessories or is poorly maintained, the
vibration emission may differ. This may significantly increase the
exposure level over the total working period.

Based on the results the E-tool can be used to cut out 9 windscreens
which have an average actual cutting time of 5 minutes each (9 x
5min = 45min) to stay within the 46min EAV limit without requiring
the implementation of management programs to reduce exposure
and risk.
An estimation of the level of exposure to vibration should also take
into account the times when the tool is switched off or when it is
free running but not actually doing the job. This may significantly
reduce the exposure level over the total working period.
Additional safety measures to protect the operator from the effects
of vibration include: maintaining the tool and the accessories,
keeping hands warm, organisation of work patterns, adhering to a
duty cycle times for heavy duty work. Refer to section
1.5.1 Tool Duty
Cycle Times
.
Testing carried out at BTB Tools by Computerised Bearing Analysis
(Aust) Pty Ltd identified the main operational factors that contribute
to high vibration levels during use of the E-Tool:
• Excessively pushing or forcing the tool and blade rather than
letting the tool do the cutting.
• Forcing the cutting process until the blade jams in the adhesive.
• Not applying cutting lubrication regularly as instructed or
improperly applying it prior to cutting.
• Using the wrong blade or not aligning the blade tip correctly.
• Contact with metal body (e.g. pinchweld) or mouldings and
fittings of the car.
• Using blades that have not been kept sharp.
• Using blades that are not specified to fit the BTB system.
BTB Tools recommends against all of above.

1.5 Power Tool Operation
1.5.1 Tool Duty Cycle Times & Overload Shut Down
BTB’s E-Tool is designed for technicians carrying out in-shop and
mobile domestic vehicle glass removals, with short/quick actual
cutting periods e.g. 2- 8 minutes (average 5 minutes) per job.
When used efficiently and appropriately, BTB’s E-Tool is also
excellent for incidental bus / train glass cut-outs and bonded panel
removals. These applications often involve wide and hard adhesive
and large, thick, rigid glasses requiring heavy duty continuous
cutting, which may result in excessive heat build-up. If this happens,
BTB recommend 10-15 minutes of continuous cutting then to
stop the tool to allow an adequate cooling down period before
continuing. The tool incorporates an
overload protection feature
and will shut down repeatedly if overloaded. The tool will re-start by
releasing and re-engaging the On/Off slide trigger.
Faster cut-out and longer life-span of the tool results when the
E-Tool is operated efficiently and used as instructed, including the
use of cutting lubrication. Inefficient use with lack of lubrication and
overloading of the E-Tool will result in a slower cut-out and a shorter
tool life span of the tool.
Repeated overload may void warranty of the tool if evidenced by
the diagnostic feature of the E-Tool. Refer to section
1.0.2 Warranty
and Serial Number Location (Page 3)
.
1.5.2 Power On/Off Slide Trigger
The slide action trigger caters for multiple hand locations. Finger
pressure locks at the front, centre and rear of the trigger hold the
tool in the ON position. Auto OFF with trigger release.
