Operating Instructions for Vibration Reduced Air Tools
Contents
1. Whilst looking at the cutting tool which Is resting against the work surface squeeze the throttle lever slowly When the tool starts to run maintain only enough forward force on the handle and plastic cover of the machine to prevent the cutting tool from bouncing around on the work surface If too much forward feed force is applied to the pick vibration transfer levels will increase and the pick will operate less efficiently After a few pro active runs you will get a feel for the correct load to apply to ensure the cutting tool does not bounce and penetrates the work surface During operation of the tool make sure it does not contact any part of your body other than your hands MOVE THE TOOL OFTEN After the angled cutting faces of the cutting tool have entered the work surface the rate of cutting tool penetration of the work surface decreases substantially Therefore reduce vibration exposure by moving the cutting tool every 8 to 10 seconds to avoid jamming the cutting tool in the work surface STOP THE PICK WHEN MOVING THE CUTTING TOOL POSITION The throttle should be released and with one hand underneath the pick handle and the other gripping the plastic body lift the pick to move it to the next selected cutting tool position MAKE SURE THE CUTTING TOOL DOES NOT BECOME JAMMED The main cause of jamming or sticking of the cutting tool especially in concrete surfaces is by trying to remov2.

JOB Make sure any cutting tool you are about to use is sharp not blunt and is the correct length to enable you to adopt a comfortable stance when operating the Tool Sometimes it is best to start with a shorter cutting tool say 300mm below collar then change to a longer one say 450 or 500mm below collar as you move deeper below the work surface Don t use an asphalt or tarmac cutter when cutting concrete Use only a moil point or narrow chisel see back page for recommended types of cutting tool Always turn off the air supply and release the air in the hose before attempting to change a cutting tool moil points narrow chisels speedibust point tarmac cutter tapered tarmac cutter flat asphalt cutter 5 Chisel end asphalt cutter 3 Chisel end clay spade straight digger steel narrow digger steel wide i Make sure any cutting tool you are about to harp not blunt USE IS S Vibration Reduced Demolition Picks v Correct Operation oe gt j EN OON a 4 p N 4 4 oN 7 f a gt e nu OOo A A a S mn N nr N bO 4 N A N N k N Le A y x x 4 3 4 en N z y lt y pe L ee A gt A j Po o O ON p i apa N N PRES lt L 4 x N d N 4 N 4 A 4 A h Est RS 4 pe re 4 PEN N 4 4 i W A i A N 4
