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 and ON/OFF valve for the water Checking, maintaining and servicing the machine′′s safety equipment The switch lock is designed to prevent accidental operation of the switch. The ON/OFF valve for the water supply is also controlled with the switch lock. When the switch lock (A) is pressed in this opens the water valve and releases the switch (B). As long as the switch is pressed in the switch lock remains pressed in and the water valve open.
SAFETY INSTRUCTIONS Checking the blade guard ! General working instructions WARNING! Always check that the guard is correctly fitted before starting the machine. Also check that the blade is fitted correctly and is not damaged in anyway. A damaged blade can cause personal injuries. See instructions under the heading Assembly. ! Check that the guard is complete and without any cracks or deformations. WARNING! This section describes basic safety directions for using a power cutter.
SAFETY INSTRUCTIONS Cutting ! • Move the blade slowly backwards and forwards to give a small contact surface between the blade and material to be cut. This will mean the blade temperature is kept down resulting in efficient cutting. • Feed the machine in line with the blade. Side pressure can destroy the blade and is extremely dangerous. WARNING! The safety distance for the power cutter is 15 metres. You are responsible to ensure that animals and onlookers are not within the working area.
SAFETY INSTRUCTIONS Large work How to avoid kickback Cuts exceeding 1 m - secure a batten along the line to be cut. The batten acts as a guide. Use this guide to make a marking cut along the entire length of the cut, 50-70 mm (2-3 inches) in depth. Remove the guides once the marking cut has been made. ! WARNING! Kickback can happen very suddenly and violently; kicking the power cutter and cutting blade back at the user.
SAFETY INSTRUCTIONS • 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. ! WARNING! Cutting plastics with a diamond blade can cause kickback when the material melts due to the heat produced when cutting and sticks to the blade. 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.
SETTINGS AND ADJUSTMENTS Drive On account of the machine’s unique design the driving power is not transferred at the centre of the blade. The flanges on the two guide rollers run in the blade’s grooves. Springs on the guide rollers press out the rollers, which in turn press the Vshaped edge on the inside diameter of the blade against the V-shaped groove in the drive wheel. The drive wheel is fitted on an axle which is driven by the hydraulic motor.
SETTINGS AND ADJUSTMENTS • Loosen the knob to offload the springs. • Fit the support roller guard and ensure that the flanges on the guide rollers still enter the blade’s grooves correctly. Now tighten the three screws fully. • Pull out the lock for the front handle and move the handle to the service position. • Rotate the blade and make sure that the support rollers are not clamped against the blade.
SETTINGS AND ADJUSTMENTS CAUTION! The machine should be upright. If the machine lies on its side the weight of the blade makes it difficult to make a correct adjustment. • Water hose Connect the water hose to the water supply. The water flow is activated by opening the check valve. Minimum water flow: 4 l/min Note that the machine’s hose nipple is fitted with a filter. Tighten the knobs fully and the machine is ready to use. Water supply When you press in the switch lock (A) the water valve opens.
STARTING AND STOPPING Starting and stopping ! WARNING! Note the following before starting: Make sure you are standing properly and that the blade can not come into contact with anything. Keep people and animals well away from the working area. Check that the power source (the hydraulic unit) supplies the correct oil flow and oil pressure. 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.
MAINTENANCE Maintenance ! • • The guide roller can now be pulled out of the chassis WARNING! Inspection and/or maintenance should be carried out with the hydraulic hoses disconnected. Dismantling the complete guide roller • • Assembling the complete guide roller • Screw the knob until it bottoms, and then loosen the knob 2 turns. • Insert the guide roller in the chassis • Now press the guide roller into the knob. Remove the support roller cover. Lift off the blade. Unscrew the knob.
MAINTENANCE Drive wheel 1 Lock the axle using the locking button. See the instructions under the heading What is what?. 2 Loosen the centre screw and remove the washer. B) Worn • Replace the support rollers when the roller surface is flat, (or) when the groove on the roller surface has worn away. A) New B) Worn 3 You can now lift off the drive wheel. CAUTION! Replace the drive wheel when fitting a new blade. A worn drive wheel can result in the blade slipping and becoming damaged.
MAINTENANCE Reconstructing the blade ! WARNING! Ring cutter blades must not be reconstructed. Due to its design, a ring cutter blade is exposed to other strains than a centre driven 14 inch diamond blade. Firstly, the drive wheel is driven on the inner diameter of the blade so that both the surfaces of the drive wheel and the blade are exposed to wear. The core of the blade becomes thinner and the guide wider, which prevents the blade being driven by the wheel.
MAINTENANCE Maintenance schedule CAUTION! The chart is based on daily use of the equipment. Daily Twice a week Support and guide rollers Check the support rollers with regard to wear. X Check the guide rollers with regard to wear. X Lubricate the guide rollers. X Hydraulic System Inspect the hydraulic hoses. X Inspect and clean the water nozzle. X Drive system Check the condition of the drive wheel. X Water system Inspect and clean the water nozzles on the water disc.
TROUBLE SHOOTING Mechanics Symptom The blade does not rotate. Probable cause Roller knobs not tightened fully. The blade not fitted on guide rollers correctly. Rollers tensioned too much. Possible faulty hose connection to the hydraulic system. Possible faulty hose connection to the drive source or other hydraulic problem. The blade rotates too slowly. Roller knobs not tightened fully. Worn drive wheel. The V-shaped inner diameter of the blade is worn. The springs on the guide rollers are weakened.
