OPERATOR SAFETY/WARNINGS
0034
Tool operators must always comply with safety precautions listed here and on stickers and tags attached to tool and hose.
These safety precautions are given for your safety. Review them carefully before operating tool and before performing general
maintenance or repairs. Failure to do so could result in personal injury or equipment damage.
WARNING
Operator must start in work area without bystanders. Flying debris can cause serious injury.
Always wear safety equipment such as goggles, ear and head protection, and safety shoes at all
times when operating tool. Use gloves and aprons when necessary.
Operator must be familiar with all prohibited work areas such as excessive slopes and dangerous
terrain conditions.
Maintain proper footing and balance at all times.
Do not inspect or clean tool while hydraulic power source is connected. Accidental engagement of
tool can cause serious injury.
Always connect hoses to tool hose couplers before energizing hydraulic power source. Be sure all
hose connections are tight and are in good condition.
Do not operate tool at oil temperatures above 140F (60C). Operation at higher temperatures can
cause higher than normal temperatures at tool which can result in operator discomfort.
Do not operate a damaged, improperly adjusted, or incompletely assembled impact wrench.
Never wear loose clothing that can get entangled in working parts of tool.
Keep all parts of your body away from rotating parts. Long hair or loose clothing can become
drawn into rotating components.
Do not reverse impact wrench rotation direction by changing fluid flow direction.
Release trigger if power supply has been interrupted.
When working near electrical conductors, always assume that all conductors are energized and that
insulation, clothing, and hoses can conduct electricity. Use hose labeled and certified as non-
conductive.
Failure to observe these warnings may result in injury or death to personnel.
