Skil 9780 AA - Manual (Page 8)

8
• Use only grinding/cutting discs with a maximum
thickness of 8 mm and a spindle hole diameter of 22
mm
• For mounting/using non-SKIL accessories observe the
instructions of the manufacturer concerned
• Never use reducors or adaptors to fit large-hole grinding/
cutting discs
• Never use accessories with a “blind” threaded hole
smaller than M14 x 21 mm
OUTDOOR USE
• Connect the tool via a fault current (FI) circuit breaker
with a triggering current of 30 mA maximum
BEFORE USE
• Before using the tool for the first time, it is recommended
to receive practical information
• Always mount auxiliary handle E 2 and protective guard
F 2; never use the tool without them
• Use suitable detectors to find hidden utility lines or
call the local utility company for assistance (contact
with electric lines can lead to fire or electrical shock;
damaging a gas line can result in an explosion;
penetrating a water pipe will cause property damage or
an electrical shock)
• Do not work materials containing asbestos (asbestos
is considered carcinogenic)
• Dust from material such as paint containing lead, some
wood species, minerals and metal may be harmful
(contact with or inhalation of the dust may cause allergic
reactions and/or respiratory diseases to the operator or
bystanders); wear a dust mask and work with a dust
extraction device when connectable
• Certain kinds of dust are classified as carcinogenic (such
as oak and beech dust) especially in conjunction with
additives for wood conditioning; wear a dust mask and
work with a dust extraction device when
connectable
• Follow the dust-related national requirements for the
materials you want to work with
• Be careful when cutting grooves, especially in supporting
walls (slots in supporting walls are subject to country-
specific regulations; these regulations are to be observed
under all circumstances)
• Secure the workpiece (a workpiece clamped with
clamping devices or in a vice is held more securely than
by hand)
• Do not clamp the tool in a vice
• Use completely unrolled and safe extension cords with a
capacity of 16 Amps (U.K. 13 Amps)
DURING USE
• Inrush currents cause short-time voltage drops; under
unfavourable power supply conditions, other equipment
may be affected (if the system impedance of the power
supply is lower than 0,104 + j0,065 Ohm, disturbances
are unlikely to occur); if you need further clarification, you
may contact your local power supply authority
• If the cord is damaged or cut through while working, do
not touch the cord, but immediately disconnect the plug
• Never use the tool when cord is damaged; have it
replaced by a qualified person
• In case of electrical or mechanical malfunction,
immediately switch off the tool and disconnect the plug
• In case of current interruption or when the plug is
accidentally pulled out, release switch H 2 in order to
prevent uncontrolled restarting
AFTER USE
• After switching off the tool, never stop the rotation of the
accessory by a lateral force applied against it
WHEN CONNECTING NEW 3-PIN PLUG (U.K. ONLY):
• Do not connect the blue (= neutral) or brown (= live) wire
in the cord of this tool to the earth terminal of the plug
• If for any reason the old plug is cut off the cord of this tool,
it must be disposed of safely and not left unattended
USE
• Mounting of accessories 2
! disconnect the plug
- clean spindle A and all parts to be mounted
- tighten clamping flange B with spanner C while
pushing spindle-lock button D
! push spindle-lock button D only when spindle A
is at a standstill
- for removing accessories handle vice-versa
! grinding/cutting discs become very hot during
use; do not touch them until they have cooled
down
! always mount backing pad when using sanding
accessories
! never use a grinding/cutting disc without the
label (“blotter”) which is glued onto it (if
provided)
• Mounting of auxiliary handle E 5
! disconnect the plug
• Removing/mounting/adjusting of protective guard F 6
! disconnect the plug
- open protective guard F by loosening screw K
- place protective guard F on the spindle collar of the
tool head and turn it to the required position
(depending on the work to be carried out)
! ensure that the closed side of the protective
guard always points to the operator
- fasten protective guard F by tightening screw K
• 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 30 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 safety switch H 7
- switch on tool 7a
! 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
- switch off tool 7b
! 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 8
- move the tool back and forth with moderate pressure
! never use a cutting disc for side grinding
