Application Advice; Maintenance & Service; Noise / Vibration - Skil 3910 Original Instructions Manual

- screw auxiliary handle E on the right, the top, or the left
of the tool (depending on the work to be carried out)
• Removing/mounting/adjusting of protective guard F q
! remove battery from tool
! ensure that the closed side of the protective guard
always points to the operator
- if necessary, adjust protective guard F by tightening
screw G which is pre-set at manufacturing (ensure
that the protective guard is closed)
• Before using the tool
- ensure that accessory is correctly mounted and firmly
tightened
- check if accessory runs freely by turning it by hand
- test-run tool for at least 60 seconds at highest no-load
speed in a safe position
- stop immediately in case of considerable vibration or
other defects and check tool to determine the cause
• On/off locking switch J w
- switch on tool w a
! be aware of the sudden impact when the tool is
switched on
! before the accessory reaches the workpiece, the
tool should run at full speed
- lock switch w b
- unlock switch/switch off tool w c
! before switching off the tool, you should lift it from
the workpiece
! the accessory continues to rotate for a short time
after the tool has been switched off
• Grinding e
- move the tool back and forth with moderate pressure
! never use a cutting disc for side grinding
• Cutting r
- do not tilt the tool while cutting
- always move the tool in same direction as arrow on tool
head, in order to prevent the tool from being pushed out
of the cut in an uncontrolled manner
- do not apply pressure on the tool; let the speed of the
cutting disc do the work
- the working speed of the cutting disc depends on the
material to be cut
- do not brake cutting discs with side pressure
Battery protection
•
Switches off the tool or reduces the speed or prevents
the tool from being switched on, when
- the load is too high
- the battery temperature is not within the allowable
operating temperature range of -20 to +50°C
- the lithium-ion battery is nearly empty (to protect
against deep discharge)
! do not continue to press the on/off switch after the
tool is switched off automatically; battery may be
damaged
• Holding and guiding the tool
- always hold the tool firmly with both hands, so you will
have full control of the tool at all times
! while working, always hold the tool at the grey-
coloured grip area(s) t
- provide for a secure stance
- pay attention to the direction of rotation; always hold the
tool so, that sparks and grinding/cutting dust fly away
from the body
- keep ventilation slots K 2 uncovered
• Mounting/removing spanner C y
- only applicable if tool is executed with auxiliary handle
with integrated spanner storage

• Always keep tool clean (especially ventilation slots K 2 )
! remove battery from tool before cleaning
• If the tool should fail despite the care taken in
manufacturing and testing procedures, please send the

waste material (only for EU countries)
- in observance of European Directive 2012/19/EC
on waste of electric and electronic equipment and
its implementation in accordance with national law,
electric tools that have reached the end of their life
must be collected separately and returned to an
environmentally compatible recycling facility
- symbol 7 will remind you of this when the need for
disposing occurs
! prior to disposal protect battery terminals with
heavy tape to prevent short-circuit

NOISE / VIBRATION

• Measured in accordance with EN 60745 the sound
pressure level of this tool is 80.5 dB(A) and the sound
power level 91.5 dB(A) (uncertainty K = 3 dB), and the
vibration when surface grinding 5.5 m/s² (triax vector
sum; uncertainty K = 1.5 m/s²)
! other applications (such as cutting-off) may have
different vibration values
• The vibration emission level has been measured in
accordance with a standardised test given in EN 60745;
it may be used to compare one tool with another and as
a preliminary assessment of exposure to vibration when
using the tool for the applications mentioned
- using the tool for different applications, or with different
or poorly maintained accessories, may significantly
increase the exposure level
- the times when the tool is switched off or when it is
running but not actually doing the job, may significantly
reduce the exposure level
! protect yourself against the effects of vibration by
maintaining the tool and its accessories, keeping
your hands warm, and organizing your work
patterns
