Wet Cutting with Diamond Cutting 
Wheels
STIHL diamond cutting wheels are 
suitable for wet cutting.
Wet cut whenever feasible. It increases 
the service life of diamond wheels, 
reduces reactive forces and will help 
control dust.
The cutting wheel must be supplied with 
at least 20 fl. oz. (0.6 liters) of water per 
minute for proper dust suppression. To 
reduce the risk of serious or fatal 
respiratory disease or other illness when 
this flow rate cannot be achieved, 
maintained or confirmed, the operator 
and any bystanders should always wear 
a NIOSH-approved respirator that is 
rated for the material being cut and 
appropriate for worksite-specific 
conditions. The respirator must have an 
Assigned Protection Factor sufficient to 
provide the level of respiratory 
protection needed for the material being 
cut and worksite-specific conditions.
Even if wet cutting at the recommended 
flow rate, an operator who is working 
with the machine for more than two 
hours in one day, along with any 
bystanders, should always wear a 
NIOSH-approved respirator that is rated 
for the material being cut and 
appropriate for worksite-specific 
conditions.
Consult your employer for information 
regarding the material you are cutting 
and your worksite conditions. Your 
employer is likely to have in place an 
OSHA-required respiratory protection 
program and can provide information 
regarding the type and level of 
respiratory protection needed for your 
worksite. Information is also available 
from OSHA at www.OSHA.gov.
Before wet cutting, make sure water will 
not damage the floor, building or other 
property, the material being cut or any 
surrounding objects. Make sure that 
"run-off" will not cause any type of 
environmental damage or come into 
contact with electrical sources.
WARNING
STIHL recommends the use of only 
STIHL-branded cutting wheels on your 
cut-off machine. Use of non-STIHL 
cutting wheels may be extremely 
dangerous. See the chapter "Reducing 
the Risk of Kickback Injury" in this 
instruction manual.
WARNING
To reduce the risk of electrocution to you 
or bystanders, do not allow water or 
sludge to contact live electric wires or 
other electrical power sources.

WARNING
To reduce the risk of injury from wheel 
breakage, never use water with a 
composite wheel that is not specifically 
designed for wet cutting.
