Stanley Black & Decker GR30 Manuel D’Utilisation

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 GR30 Hydraulic Grinder will provide safe and de-

pendable service if operated in accordance with the in-

structions given in this manual. Read and understand 

this manual and any stickers and tags attached to the 

tool and hoses before operation. Failure to do so could 

result in personal injury or equipment damage.

•  Operator must start in a work area without bystand-

ers. The operator must be familiar with all prohibited 

work areas such as excessive slopes and danger-

ous terrain conditions.

•  Establish a training program for all operators to en-

sure safe operation.

•  Do  not  operate  this  tool  without  first  reading  this 

manual.

•  Do not operate the tool unless thoroughly trained or 

under the supervision of an instructor.

•  Always wear safety equipment such as goggles, 

gloves, safety shoes, ear, breathing and head pro-

tection at all times when operating the tool.

•  Do not inspect or clean the tool while the hydraulic 

power source is connected. Accidental engagement 

of the tool can cause serious injury.

•  Always connect hoses to the tool hose couplers be-

fore energizing the hydraulic power source. Be sure 

all hose connections are tight.

•  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 and may 

cause damage to the tool.

•  Do not operate a damaged, improperly adjusted, or 

incompletely assembled tool.

•  To avoid personal injury or equipment damage, all 

tool repair, maintenance and service must only be 

performed by authorized and properly trained per-

sonnel.

•   Always replace parts with replacement parts recom-

mended by Stanley Hydraulic Tools. 

•  Check fastener tightness often and before each use 

daily.

•  Do not tighten or loosen the wheel nut by impact. 

Hold the shaft with a second wrench on the the flats 

behind the wheel and tighten securely.

•  Do not overreach. Maintain proper footing and bal-

ance at all times.

•  Always hold the tool with both hands when the unit 

is running. Use a firm grip.

•  Keep all parts of your body away from the rotating 

wheel.

•  Do not wear loose clothing or unbound long hair 

when operating the tool. Loose items can get en-

tangled with the tool and cause serious injury.

•  Supply hoses must have a minimum working pres-

sure rating of 2500 psi/175 bar.

•  The hydraulic circuit control valve must be in the 

“OFF” position when coupling or uncoupling the tool. 

Wipe all couplers clear before connecting. Failure to 

do so may result in damage to the quick couplers 

and cause overheating. Use only lint-free cloths.

•  Do not exceed the rated limits of the tool or use the 

tool for applications beyond its design capacity.

•  Always keep critical tool markings, such as labels 

and warning stickers, legible.

•  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.
