SAFETY INSTRUCTIONS Steps before using a new power cutter. • This machine is a hydraulically operated power cutter intended for free-hand cutting. The machine should be connected to a hydraulic unit with an oil flow of 35-42 litres/min and a maximum pressure of 150 bar. • Please read the operator’s manual carefully. • Check the cutting blade’s mounting, see the chapter ”Assembly”. • Breathing mask • Heavy-duty, firm grip gloves.
SAFETY INSTRUCTIONS Switch lock Checking the switch lock The switch lock is designed to prevent accidental operation of the switch. When the lock (A) is pressed in this releases the switch (B). Check that the switch is locked when the switch lock is in its home position. A B Press the switch lock and check that it returns to its home position when released. The switch lock remains pressed as long as the switch is pressed.
SAFETY INSTRUCTIONS • Wear personal protective equipment. See instructions under the heading Personal protective equipment. • Never use a machine that has been modified in any way from its original specification. when cutting that no material can become loose and fall, causing operating injury.Take great care when working on sloping ground. • Make sure that no clothes or parts of the body come in contact with the cutting equipment when it is rotating.
SAFETY INSTRUCTIONS • Support the work piece in such a way that it is possible to predict what will happen, and so that the cut remains open while cutting. Sharpening diamond blades Diamond blades can become dull when the wrong feeding pressure is used or when cutting certain materials such as heavily reinforced concrete. Working with a blunt diamond blade causes overheating, which can result in the diamond segments coming loose. Sharpen the blade by cutting in a soft material such as sandstone or brick.
SAFETY INSTRUCTIONS • Stand at a comfortable distance from the work piece. • Take care when inserting the blade in an existing cut. • Never cut above shoulder height. • Be alert to movement of the work piece or anything else that can occur, which could cause the cut to close and pinch the blade. Make sure that the right bushing is used for the cutting blade to be fitted on the machine. See the instructions under the heading Assembling the cutting blade. High-quality blades are often most economical.
SAFETY INSTRUCTIONS Check that the blade is approved for the same or higher speed according to the aproval plate of the engine. Never use a cutting blade with a lower speed rating than that of the power cutter. Ensure the blade it not cracked or damaged in any other way. Diamond blades for wet cutting ! WARNING! Cool diamond blades for wet cutting continuously with water to prevent overheating, which can cause the blade to break up and eject pieces that can cause injury.
ASSEMBLY Assembly ! WARNING! Always disconnect the machine from the hydraulic hoses before cleaning, assembly and maintenance. Fitting the cutting blade Husqvarna’s blades are approved for hand-held power cutters. Blades are manufactured with three different diameters of centre holes: 20 mm (0.787"), 22.2 mm (7/8") and 25.4 mm (1"). Bushings can be fitted on the machine axle to adjust the machine to the centre hole of the blade.
STARTING AND STOPPING Starting and stopping ! WARNING! Note the following before starting: Make sure you have a secure footing and that the cutting blade cannot touch anything. Keep people and animals well away from the working area. Starting • Grip the front handle with the left hand. • Grip the rear handle with the right hand. When you grip the rear handle this releases the switch lock. Stopping The machine is stopped by releasing the switch.
MAINTENANCE Maintenance ! WARNING! Inspection and/or maintenance should be carried out with the hydraulic hoses disconnected. Checking the drive axle and flange washers Check that the threads on the drive shaft are undamaged. Check that the contact surfaces on the blade and the flange washers are undamaged, of the correct dimension, clean, and that they run properly on the drive axle. Tensioning the drive belt The drive belt is fully enclosed and well protected from dust and dirt.
MAINTENANCE Daily maintenance Carry out the following checks daily before using the machine. 1 Check that nuts and screws are tight. 2 Check that the power source (the hydraulic unit) supplies the correct oil flow and oil pressure. 3 Check that the hydraulic hoses and couplings are clean and undamaged. 4 Connect the machine hoses with the hoses from the power source. 5 Start the power source and check that the power cutter functions by starting the machine with the switch in the rear handle.
