 Manual ◄ 5

Tool operators and maintenance personnel must always 

comply with the safety precautions given in this manual 

and on the stickers and tags attached to the tool and 

hose.
These safety precautions are given for your safety. Re-

view them carefully before operating the tool and before 

performing general maintenance or repairs.
Supervising personnel should develop additional pre-

cautions  relating  to  the  specific  work  area  and  local 

safety regulations. If so, place the added precautions in 

the space provided in this manual.
The model HG80 Hydraulic Grinder will provide safe 

and dependable service if operated in accordance with 

the instructions given in this manual. Read and under-

stand this manual and any stickers and tags attached 

to the grinder and hose before operation. Failure to do 

so could result in personal injury or equipment damage.

• 

The operator must start in a work area without by-

standers. Flying debris can cause serious injury.

• 

Do not operate the tool unless thoroughly trained 

or under the supervision of an instructor. Establish 

a training program for all operators to ensure safe 

operation.

• 

Always wear safety equipment such as goggles, ear 

and head protection, and safety shoes at all times 

when operating the tool. Use gloves and aprons 

when necessary.

• 

The operator must be familiar with all prohibited 

work areas such as excessive slopes and danger-

ous terrain conditions.

• 

Do not inspect, clean or replace the grinding wheel 

while the hydraulic power source is connected. Do 

not inspect or clean the tool while the hydraulic pow-

er source is connected. Accidental engagement of 

the tool can cause serious in jury.

• 

Always connect hoses to the tool hose couplers be-

fore energizing the hydraulic power source. Be sure 

all hose connections are tight and are in good condi-

tion.

• 

Do not operate the tool at oil temperatures above 

140 °F/60 °C. Operation at higher temperatures can 

cause higher than normal temperatures at the tool 

which can result in operator discomfort.

• 

Do not operate the tool with the wheel guard re-

moved.

• 

Do not operate a damaged, improperly adjusted, or 

incompletely assembled grinder.

• 

Never wear loose clothing that can get entangled in 

the working parts of the tool.

• 

Keep all parts of your body away from the rotat-

ing wheel. Long hair or loose clothing can become 

drawn into rotating components.

• 

Keep the wheel off all surfaces when starting the 

grinder.

• 

Do not use a wheel that is cracked, chipped or oth-

erwise damaged. Always inspect wheels for pos-

sible damage before installation or use.

•  Always use wheels that conform to the specifications 

given in the OPERATION section of this manual.

• 

Do not reverse grinding wheel rotation direction by 

changing fluid flow direction.

• 

Do not move the tool until the wheel has stopped 

rotating. Release the trigger if the power supply has 

been interrupted.

• 

To avoid personal injury or equipment damage, all 

tool repair, maintenance and service must only be 

performed by authorized and properly trained per-

sonnel.

• 

If the material being ground creates an emission of 

dust and fumes, use personal protective devices.

• 

Never cock, jam or wedge the grinding wheel during 

operation.

•  Never cause sparks in the vicinity of flammable ma

-

terials.

• 

Eye injury, and cutting or severing of body parts is 

possible if proper procedures are not followed.

• 

Warning:

 Use of this tool on certain materials during 

demolition could generate dust potentially contain-

ing a variety of hazardous substances such as as-

bestos, silica or lead.  Inhalation of dust containing 

these or other hazardous substances could result 

in serious injury, cancer or death. Protect yourself 

and those around you. Research and understand 

the materials you are cutting.  Follow correct safety 

procedures and comply with all applicable national, 

state or provisional health and safety regulations 

relating to them, including, if appropriate arranging 

for the safe disposal of the materials by a qualified 

person.
