INTRODUCTION The CAT47 is a professional, 2-hammer, 1” square drive impact wrench with an extended anvil. 1. 1” Square Socket Drive 2. Side handle 3. Forward/Reverse clutch 4. Airline Connection 5. Trigger 1 2 3 4 5 AIR SUPPLY REQUIREMENTS WARNING: COMPRESSED AIR CAN BE DANGEROUS. ENSURE THAT YOU ARE THOROUGHLY FAMILIAR WITH ALL PRECAUTIONS RELATING TO THE USE OF COMPRESSORS AND COMPRESSED AIR SUPPLY. • Use only clean, dry, regulated compressed air as a power source.
• A pressure of 90 psi with a flow of 7.44 cfm is required. Too high an air pressure will shorten the life of the tool due to excessive wear. A typical airline layout is shown. If an automatic in-line filter/regulator/lubricator unit is used it will keep the tool in good condition, but should be regularly checked and topped up with oil.
OPERATION CAUTION: ALWAYS BE SURE THAT THE TOOL IS OFF BEFORE ATTACHING OR REMOVING A SOCKET. ALWAYS TAKE CARE TO USE THE CORRECT SIZE SOCKET FOR BOLTS AND NUTS. AN INCORRECT SOCKET WILL CAUSE DAMAGE TO THE BOLT OR NUT. 1. The side handle is supplied loose and must be fitted to the impact wrench using the bolt provided. 2. Select an appropriate impact socket, which must be in good condition, and fits the anvil and nut closely. Use only 1”square drive impact wrench sockets. (NEVER use standard hand sockets).
LOOSENING A WHEEL NUT 1. Remove any wheel trim, before selecting the appropriate socket and placing firmly on the square drive of the wrench. 2. With the FORWARD/NEUTRAL/REVERSE switch in the REVERSE running position, and holding the wrench firmly in BOTH HANDS, pull the trigger. The nut will be impacted repeatedly until it is loosened. IMPORTANT! Release the trigger immediately the nut begins to loosen. 3.
2. If no line lubricator is used, ensure that oil is applied to the tool on a daily basis through the air inlet connection. 3. For lubricating the air motor, an air line lubricator should be used, containing Clarke Air Line Oil, adjusted to 2 drops per minute. If this is not possible, run a few drops of oil through the tool. It may be entered into the tool air inlet, (ensuring the strainer is clear), or into the hose at the nearest connection to the air supply. Then operate the tool.
STORAGE 1. Store the tool safely in its box in a dry, secure environment. 2. If the tool is not to be used for longer than 24 hours, run a few drops of Clarke airline oil into the air inlet and run the tool for a few seconds to ensure that the oil has been well distributed throughout the tool. 3. When storing, ensure the blanking plug is replaced on the airline connector once the airline has been disconnected. **Clarke Airline Oil is available from your Clarke dealer: Part no 3050825.

VIBRATION EMISSIONS HAND-ARM VIBRATION Employers are advised to refer to the HSE publication “Guide for Employers”. All hand held power tools vibrate to some extent, and this vibration is transmitted to the operator via the handle, or hand used to steady the tool. Vibration from about 2 to 1500 herz is potentially damaging and is most hazardous in the range from about 5 to 20 herz.
You will note that a third value is given in the specification - the highest measured reading in a single plane. This is the maximum level of vibration measured during testing in one of the axes, and this should also be taken into account when making a risk assessment. ‘a’ values in excess of 2.5 m/s2 are considered hazardous when used for prolonged periods. A tool with a vibration value of 2.8 m/s2 may be used for up to 8 hours (cumulative) per day, whereas a tool with a value of 11.
