Husqvarna K760 Rescue manual Managing dust, Training and protective equipment

OPERATING

•Maintain a safe distance from the cutting blade when the engine is running.

•Never leave the machine unsupervised with the motor running.

•Never move the machine when the cutting equipment is rotating. The machine is equipped with a friction retarder to shorten the blade stop time.

•The guard for the cutting equipment should be adjusted so that the rear section is flush with the work piece. Spatter and sparks from the material being cut are then collected up by the guard and led away from the user. The guards for the cutting equipment must always be fitted when the machine is running.

•Never use the kickback zone of the blade for cutting. See instructions under the heading "Kickback".

•Keep a good balance and a firm foothold.

•Never cut above shoulder height.

•Never cut from a ladder. Use a platform or scaffold if the cut is above shoulder height. Do not overreach

•Stand at a comfortable distance from the work piece.

•Check that the blade is not in contact with anything when the machine is started

•Apply the cutting blade gently with high rotating speed (full throttle) Maintain full speed until cutting is complete.

•Let the machine work without forcing or pressing the blade.

•Feed down the machine in line with the blade. Pressure from the side can damage the blade and is very dangerous.

•Move the blade slowly forwards and backwards to achieve a small contact area between the blade and the material to be cut.This reduces the temperature of the blade and ensures effective cutting.

Managing dust

The machine is fitted with DEX (Dust Extinguisher), a low flushing water kit that offers maximum dust suppression.

Use wet cutting blades with DEX when possible for optimal dust management. See instructions in the section "Cutting blades".

Adjust water flow using the tap to bind the cutting dust. The volume of water required varies depending on the type of job at hand.

If water hoses loosen from their supply sources, this indicates that the machine is connected to a water pressure that is too high. See instructions under the "Technical data" heading for recommended water pressure.

Cutting with toothed/carbide tipped blades during rescue operaions

WARNING! A power cutter should never

! be used with carbide tipped blade for non-emergency work, such as in the construction trades.

Be aware at all times that carbide tipped blades are more kickback prone than abrasive or diamond blades if not used properly.

If the public safety force (fire department) that purchased this power cutter has decided to equip this unit with a carbide tipped blade for rescue operations, the following safety considerations must be adhered to.

Training and protective equipment

•Only operators trained in the use of cutting with a power cutter equipped with carbide tipped blade shall be allowed to operate the power cutter.

•Full protective fire fighting gear shall be worn by the operator at all times.

•A full face shield (not just protective eye glasses) shall be worn by the operator to protect the face from flying debris or a sudden kick-back of the power cutter.
