Festool HK 85 EB, Original Instructions Manual

–
Always observe that the lower guard is
covering the blade before placing the saw
down on bench or floor. An unprotected,
coasting blade will cause the saw to walk
backwards, cutting whatever is in its path.
Be aware of the time it takes for the blade
to stop after switch is released.
Function of the guide wedge [1-5]
–
Use the correct saw blade for the guide
wedge, where possible. The function of the
guide wedge is restricted if using saw
blades with a thicker blade core. To en­
sure that the guide wedge functions prop­
erly, make sure the blade core of the saw
blade is thinner than the guide wedge and
that the tooth width is greater than the
thickness of the guide wedge. Expect in­
creased risk of kickback when using a
thicker saw blade.
– Do not operate the saw if the guide wedge
is bent. Even the slightest problem can
cause the guard to close more slowly.
–
Never work without a guide wedge. The
guide wedge ensures that the protective lid
opens safely and smoothly. It also reduces
the risk of a kickback and clamping saw
blade.
2.3 Safety instructions for the pre-
assembled saw blade
Usage
–
The maximum speed specified on the saw
blade must not be exceeded and the speed
range must be adhered to.
– The pre-installed saw blade is only de­
signed for use in circular saws.
– Proceed with extreme care when unpack­
ing, packing and handling the tool (e.g. in­
stalling it in the machine). There is a risk of
injury from extremely sharp cutting edges!
– When handling the tool, wearing safety
gloves provides a more secure hold of the
tool and further reduces the risk of injury.
– Circular saw blades with cracked bodies
must be replaced. Repair is not permitted.
– Circular saw blades with a combination de­
sign (soldered saw teeth) with saw tooth
thickness smaller than 1 mm must no lon­
ger be used.
– Do not use tools with visible cracks or blunt
or damaged cutting edges.
Installation and mounting
–
Tools must be clamped in such a way that
they cannot come loose during operation.
– When assembling the tools, it must be en­
sured that the clamping takes place on the
tool hub or the clamping surface of the
tool, and that the cutting edges do not
come into contact with one another or the
fixed clamps.
– Retaining screws and nuts must be tight­
ened using suitable keys, etc. and with the
torque specified by the manufacturer.
– Do not lengthen the key or tighten by hitting
with a hammer.
– The clamping surfaces must be cleaned to
remove contamination, grease, oil and wa­
ter.
– Clamping screws must be tightened ac­
cording to the manufacturer's instructions.
– Only securely installed rings, e.g. rings that
have been pressed in or those that are held
in position by an adhesive bond, may be
used to adjust the hole diameter of circular
saw blades to the spindle diameter of the
machine. The use of loose rings is not per­
mitted.
Service and maintenance
–
Repairs and sanding work may only be car­
ried out by Festool customer service work­
shops or experts.
– The tool design must not be changed.
– Deresinify and clean the tool regularly
(cleaning agent with pH between 4.5 and 8).
– Blunt edges can be resharpened on the
clamping surface to a minimum cutting
edge thickness of 1 mm.
– Only transport the tool in suitable packag­
ing – risk of injury!
2.4 Further safety instructions
– This power tool cannot be installed in a
work bench. The power tool may become
unsafe and cause serious accidents if in­
stalled in benches from other manufactur­
ers or self-manufactured work benches.
–
Never place your hands into the chip ejec­
tor. You may injure yourself on rotating
parts.
–
Use appropriate detection devices to look
for any hidden supply lines or consult your
local utility company. If the insertion tool
makes contact with live cables, it can result
in fire and electric shock. Damage to a gas
