Skil 3910 Original Instructions Manual page 12

carefully re-enter the cut. The wheel may bind, walk up
or kickback if the power tool is restarted in the workpiece.
e) Support panels or any oversized workpiece to
minimize the risk of wheel pinching and kickback.
Large workpieces tend to sag under their own weight.
Supports must be placed under the workpiece near the
line of cut and near the edge of the workpiece on both
sides of the wheel.
f) Use extra caution when making a "pocket cut" into
existing walls or other blind areas. The protruding
wheel may cut gas or water pipes, electrical wiring or
objects that can cause kickback.

ACCESSORIES
• SKIL can assure flawless functioning of the tool only
when original accessories are used
• For mounting/using non-SKIL accessories observe the
instructions of the manufacturer concerned
• Use only grinding/cutting discs with a maximum
thickness of 6 mm and a spindle hole diameter of
22 mm
• Never use reducors or adaptors to fit large-hole grinding/

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

(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
