h) Do not restart the cutting operation 
in the workpiece. Let the wheel 
reach full speed and carefully re-
enter the cut. The wheel may bind, 
walk up or kickback if the power tool 
is restarted in the workpiece.
i) 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.
j) 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.
Water connection
– A water attachment kit is mounted 
on the machine for use with all types 
of water supply.
– A pressurized 2.6 gallons (10 liter) 
water tank is available from STIHL 
for wet cutting.
Use clean water for binding dust.
Most diamond cutting wheels are 
suitable for wet cutting
Wet cut whenever feasible. It increases 
the service life and cutting speed of 
diamond cutting wheels.
Ensure that the cutting wheel is 
generously supplied with water.
Wet cutting helps to suppress dust. The 
water binds the dust. The cutting wheel 
must be supplied with at least 20 fl. oz 
(0.6 liters) water per minute.
Wet cutting can also reduce the energy 
of reactive forces. In a pinch situation, 
the water can act as a lubricant.
Composite resin wheels can be used for 
dry cutting of metals or for wet or dry 
cutting of concrete, stone or masonry.
Composite resin wheels designed for 
dry cutting
Special procedures must be followed 
when wet cutting with a composite non-
diamond wheel designed for dry cutting. 
See the section entitled "Wet Cutting 
with Abrasive Wheels" in the safety 
precautions of this manual. Wet cutting 
is generally not suitable for cutting 
metals.
Composite resin wheels designed for 
wet cutting
If the water flow rate is too high, the 
cutting wheel may skim on the water 
surface in the cut and greatly reduce 
cutting performance. To avoid this, do 
not exceed a water flow rate of about 
135 fl. oz (4 L/min).
Use water properly:
1. Make certain water does not flow on 
wheel that is not running, since a 
composite wheel will absorb water 
and that will affect wheel balance.
2. After finishing work, run the cutting 
wheel at normal operating speed for 
about 3 to 6 seconds without water 
so that the remaining water is flung 
off.
Respiratory protection 
WARNING
If wet cutting at the recommended flow 
rate is not utilized, the operator and any 
bystanders should always wear a 
respirator approved by NIOSH/MSHA 
for the material being cut. Even if wet 
cutting, an operator who is actively 
Sample applications
Adjust water flow rate 
during cutting so it is suf-
ficient to bind all the dust 
that occurs (at least 
20 fl. oz (0.6 L/min)).
