2.1.3 Additional safety instructions
Personal safety
▶ Use the tool only when it is in perfect working order.
▶ Never tamper with or modify the power tool in any way.
▶ Always hold the tool firmly with both hands on the grips provided. Keep the grips dry, clean and
free from oil and grease.
▶ When working, always guide the supply cord and the extension cable to the rear and away from
the power tool. This reduces the risk of tripping over cables while work is in progress.
▶ Use a dust extractor, respiratory protection and protective goggles. Dust produced by sanding can
damage the lungs and the eyes.
▶ Take breaks between working and do relaxation and finger exercises to improve the blood
circulation in your fingers.
▶ Dust from materials such as lead-based paint, certain types of wood and concrete/masonry/stone
containing quartz, minerals or metal can be harmful to health. Contact with or inhalation of the dust can
cause allergic reactions and/or respiratory or other diseases among operators or bystanders. Certain
kinds of dust such as oakwood and beechwood dust are classified as carcinogenic, especially in
conjunction with additives for wood conditioning (chromate, wood preservative). Only specialists are
permitted to handle material containing asbestos. Use a dust extractor whenever possible. To
achieve a high level of dust collection, use a suitable dust extractor. If necessary, wear a respirator
appropriate for the type of dust generated. Ensure that the workplace is well ventilated. Comply
with national regulations applicable to the materials you will be working with.
▶ The power tool is not intended for use by debilitated persons who have received no special training.
Keep the power tool out of reach of children.
▶ Children are not permitted to play with the device and must be instructed accordingly.
Electrical safety
▶ Check the machine's supply cord at regular intervals and have it replaced by a qualified specialist if
found to be damaged. If the machine's supply cord is damaged it must be replaced with a specially
prepared and approved supply cord available from Hilti Customer Service. Check extension cords
at regular intervals and replace them if found to be damaged. Do not touch the supply cord or
extension cord if it is damaged while working. Disconnect the supply cord plug from the power
outlet. Damaged supply cords or extension cords present a risk of electric shock.
▶ Switch the electric tool off and unplug the supply cord in the event of an interruption in the electric
supply in order to avoid inadvertent restarting when the power returns.
▶ Have dirtied or dusty power tools that are used frequently for working on conductive materials
checked at regular intervals by a Hilti Service Center. Dust, especially dust from conductive materials,
or dampness on the surface of the power tool can, under unfavorable conditions, lead to electric shock.
Power tool use and care
▶ Secure the workpiece. A workpiece clamped in a vice or secured by some other clamping devices
is more secure than when held only by hand.
▶ Wear protective gloves when changing accessory tools as they get hot during use.
