CONNECT TO WATER SUPPLY
Following are the basic instructions for correct water supply to the
power cutter.
Inadequate water can result in increased potential for harmful airborne
particulates.
ICS® power cutters require a continuous water supply to the guidebar and
chain for the key purposes of cooling, lubrication and dust suppression. The
potential for airborne particulates depends on many factors including, but not
limited to, the material being cut, application and cutting environment.
NOTE: Local and/or regional regulation can vary widely. It is the responsibility
of the operator to wear appropriate dust protection applicable in their area and
suitable to the application.
Insufficient water supply will result in excessive chain stretch and may
cause chain breakage, damage to the guidebar, nose sprocket and drive
sprocket.
Never operate the power cutter with insufficient water supply. In all cases,
assure that the water supply is delivering 1.5 bar (20 psi) pressure to the power
cutter at a minimum flow rate of 4 lpm (1gpm).
CAUTION
Attach to water supply capable of delivering 1.5 bar (20 psi)
pressure to
the power cutter at a minimum flow rate of 4 lpm (1 gpm). The single
most important factor an operator can control to increase chain life is
to use adequate water pressure.
