Bayonet Fuel Filler Cap
Never use a tool to open or close the
bayonet fuel filler cap, as this could
damage the cap and cause fuel to leak
out.
The bayonet fuel filler cap must be
closed with care after refuelling.
WARNING
Never attempt to force the cap open by
using a tool. It may damage the cap and
allow fuel to leak.
Before Starting
Take off the chain guard (scabbard) and
inspect the concrete cutter for proper
condition and operation. (See the
maintenance chart near the end of the
instruction manual.)
WARNING
Always check your power tool for proper
condition and operation before starting,
particularly the throttle trigger, throttle
trigger lockout, stop switch and cutting
tool. The throttle trigger must move
freely and always spring back to the idle
position. Never attempt to modify the
controls or safety devices.
WARNING
Check fuel system for leaks, especially
the visible parts, e.g., filler cap, hose
connections, manual fuel pump (only for
power tools equipped with a manual fuel
pump). Do not start the engine if there
are fuel leaks or the fuel system is
damaged – risk of fire. Have the
machine repaired by a servicing dealer
before using it.
WARNING
Never operate your concrete cutter
without a front hand guard. This guard
helps protect your left hand.
WARNING
Never operate your power tool if it is
damaged, improperly adjusted or
maintained, or not completely or
securely assembled.
For proper assembly of the bar and
chain follow the procedure described in
the chapter "Mounting the Bar and
Diamond Abrasive Chain" of your
instruction manual. Diamond abrasive
chain, guide bar and sprocket must
match each other in gauge and pitch.
Before replacing any bar and chain, see
the chapter entitled "Specifications" in
the instruction manual.
WARNING
Always check the diamond abrasive
chain before use. Look for cracks and
make sure, that it is undamaged and in
good condition and that no pieces have
broken off.
WARNING
Proper tension of the chain is extremely
important. In order to avoid improper
setting, the tensioning procedure must
be followed as described in your
manual. Always make sure the
hexagonal nut(s) for the sprocket cover
is (are) tightened securely after
tensioning the chain in order to secure
the bar. Never start the concrete cutter
with the sprocket cover loose. Check
chain tension once more after having
tightened the nut(s) and thereafter at
regular intervals (whenever the concrete
cutter is shut off). If the chain becomes
loose while cutting, shut off the engine
and then tighten the chain. Never try to
adjust the chain while the engine is
running.
Keep the handles clean and dry; it is
particularly important to keep them free
of oil, fuel mix and grease in order for
you to maintain a firm grip and properly
control your power tool.
WARNING
Check that the spark plug boot is
securely mounted on the spark plug – a
loose boot may cause arcing that could
ignite combustible fumes and cause a
fire.
Starting
WARNING
To reduce the risk of fire and burn
injuries, start the engine at least 10 feet
(3 m) from the fueling spot, outdoors
only.
