Additional Safety Instructions For Rotary Hammer; Careful Handling And Use Of Batteries - Hilti TE 4-A22 Manual Del Usuario

▶ Maintain power tools properly. Check that moving parts are in correct working order and do not
jam, and check whether any parts are broken or so damaged that correct operation of the power
tool cannot be guaranteed. If any parts are damaged, have these parts repaired before using the
tool. Many accidents are caused by poorly maintained power tools.
▶ Keep cutting tools sharp and clean. Properly maintained tools with sharp cutting edges are less likely
to jam and are easier to control.
Using and handling the cordless power tool
▶ Use only the specified batteries in the power tools. Use of any other batteries may present a risk of
injury and fire.
▶ Recharge the batteries only with the chargers specified by the manufacturer. A charger that is
suitable for a certain type of battery may present a risk of fire when used with other types of battery.
▶ When the battery is not in use, keep it away from other metal objects such as paper clips, coins,
keys, nails, screws, or other small metal objects that could cause bridging between the terminals.
A short circuit between the battery terminals may cause burns or a fire.
▶ Liquid may leak from the battery if used incorrectly. Avoid contact with this liquid. Liquid leaking
from the battery may cause skin irritation or burns. If contact accidentally occurs, rinse with water. Seek
medical attention if the liquid comes into contact with the eyes.

2.2 Additional safety instructions for rotary hammer

Personal safety
▶ Use the product only when it is in technically faultless condition.
▶ Never tamper with or modify the power tool in any way.
▶ Use the auxiliary grips supplied with the tool. Loss of control can cause personal injury.
▶ Apply appropriate safety measures at the opposite side of the workpiece in work that involves breaking
through. Parts breaking away could fall out and / or fall down causing injury to other persons.
▶ Always hold the power tool with both hands on the grips provided. Keep the grips clean and dry.
▶ Hold the power tool by the insulated gripping surfaces when performing work in which the accessory
tool might come into contact with concealed wiring. If the accessory tool comes into contact with a live
wire, metal parts of the power tool can also become live, resulting in an electric shock.
▶ Avoid touching rotating parts – risk of injury!
▶ Wear suitable protective glasses, a hard hat, ear defenders, protective gloves and light respiratory
protection while using the power tool.
▶ Wear protective gloves also when changing the accessory tool. Touching the accessory tool presents a
risk of injury (cuts or burns).
▶ Wear eye protection. Flying fragments present a risk of injury to the body and eyes.
▶ Before starting work, check the hazard class of the dust that will be produced when working. Use
an industrial vacuum cleaner with an officially approved protection class in compliance with the locally
applicable dust protection regulations. 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.
▶ Make sure that the workplace is well ventilated and, where necessary, wear a respirator appropriate for
the type of dust generated. Contact with or inhalation of the dust can cause allergic reactions and/or
respiratory or other diseases to the operator 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.
▶ Take breaks and do physical exercises to improve the blood circulation in your fingers. Exposure to
vibration during long periods of work can lead to disorders of the blood vessels and nervous system in
the fingers, hands and wrists.
Electrical safety
▶ Before beginning work, check the working area for concealed electric cables, gas pipes and water
pipes. External metal parts of the power tool can become live, presenting a risk of electric shock, if you
accidentally damage an electric cable.
Power tool use and care
▶ Immediately switch off the power tool if the accessory tool jams. The power tool might twist off-line.
▶ Wait until the power tool stops completely before you lay it down.

2.3 Careful handling and use of batteries

▶ Observe the special guidelines applicable to the transport, storage and use of lithium-ion batteries.
▶ Do not expose batteries to high temperatures, direct sunlight or fire.
