Never use the pruning saw to cut metal, plastic, masonry or non-wood building materials. ·Use extreme caution when cutting thin branches, vines or small underbrush. The slender material may catch the saw chain and be whipped toward you ·Store pruning saw when not in use. Pruning saw should be stored in a dry and high or locked area out of the reach of children. When storing pruning saw place the scabbard on the bar and chain. ·Battery operated units do not have to be plugged into an electrical outlet; therefore, they are always in operating condition. Be aware of possible hazards even when unit is not operating. ·Save these instructions. Refer to them frequently and use them to instruct others who may use this product. If you loan someone this product, loan them these instructions also. ·After each use, clean the machine with a soft dry cloth. Remove any chips, dirt and debris in the battery bay. ·Follow the manufacturer's sharpening and maintenance instructions for the saw chain. Decreasing the depth gauge height can lead to increased kickback. ·Always use common sense and be cautious when using tools. It is not possible to anticipate every situation that could result in a dangerous outcome. Do not use this tool if you do not understand these operating instructions or you feel the work is beyond your capability; contact MILWAUKEE® Tool or a trained professional for additional information or training. ·Maintain labels and nameplates. These carry important information. If unreadable or missing, contact a MILWAUKEE® service facility for a replacement. WARNING Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are: ·lead from lead-based paint ·crystalline silica from bricks and cement and other masonry products, and ·arsenic and chromium from chemically-treated lumber. Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to ADDITIONAL BATTERY SAFETY RULES WARNING To reduce the risk of fire, personal injury , and product damage due to a short circuit, never immerse your tool, battery pack or charger in fluid or allow a fluid to flow inside them. Corrosive or conductive fluids, such as seawater , certain industrial chemicals, and bleach or bleach-containing products, etc., can cause a short circuit.

Removing/Inserting the Battery To remove the battery, push in the release buttons and pull the battery pack away from the tool. WARNING Always remove battery pack before changing or removing accessories. To insert the battery, slide the pack into the body of the tool. Make sure it latches securely into place. WARNING Only use accessories recommended for this tool. Others may be hazardous. Replacing/Adjusting the Saw Chain and Bar WARNING Always remove battery pack before changing or removing accessories. CAUTION Chain is sharp. Always wear protective gloves when handling the chain. Use Low Kickback Saw Chains - The rakers (depth gauges) ahead of each cutter can minimise the force of a kickback reaction by preventing the cutters from digging in too deeply at the kickback zone. Only use replacement chain that is equivalent to original per ANSI B175.1. 5 As saw chains are sharpened during their useful life, they lose some of the low kickback qualities and extra caution should be used. 1. Remove the battery pack. 3. Remove the drive cover by removing the guide bar nuts using the adjustment tool. · Do not over-tension the chain - excess tension will cause excessive wear and will reduce the life of the chain and could damage the bar. · New chains could stretch and loosen during initial use. NOTE: Remove battery pack and 4. Loosen the chain by turning the chain tensioning screw counterclockwise with the adjustment tool. 5. Pull the guide bar off of the guide bar bolts and unloop the chain from the drive hub. CAUTION! Saw Chain is sharp. 6. Remove the chain from the guide bar groove. CAUTION! Saw Chain is sharp. Inspect guide bar for cracks or wear; replace if damaged. 7. Wrap the new or sharpened chain around the guide bar in the direction indicated on the saw . two hours of use. 12. Tighten the guide bar nuts securely. Chain Oil WARNING Always remove battery pack before changing or removing accessories. NOTICE Fill oil reservoir with chain oil (76mL bottle is included) before starting the pruning saw and when tank is less than 1/4 full. Failure to oil the chain will cause damage to the bar and chain. each full battery discharge. Use a high quality chain oil. The oil will keep the saw chain and guide bar properly lubricated. Never run the saw without chain oil. Keep the reservoir more than 1/4 full to ensure the chain when storing to prevent rust. Always empty the oil tank when storing to prevent leakage. NOTE: It is recommended to use a vegetable based chain oil when pruning trees. Mineral oil may harm trees. Never use waste oil, automotive oil, or very thick oils. These could damage the pruning saw. Filling the Oil Reservoir 1. Remove the battery pack. 8. Ensure the chain is properly set in the slot around 2. the entire guide bar. 3. Unscrew the oil cap. 9. around the bolts. 5.

Ensure the guide bar sprocket (at the tip) rotates freely. 10. Replace the drive cover. 11. Use the adjustment tool to rotate the chain ten- sioning screw to increase tension (clockwise) until the chain is snug around the guide bar. · The tension is correct when the chain snaps back after being pulled 3 mm (1/8") away from the guide bar. No sag should be visible in the chain. · If the lubrication system still does not work properly, contact a MILWAUKEE® service facility. Transporting Saw Before transporting, always: 1. Remove the battery pack 2. Place the scabbard over the guide bar. 6 OPERATION ·Never allow any part of your body to be in line with WARNING To reduce the risk of injury, always wear proper eye protection marked to comply with AS/NZS 1337.1.

When replacing dull chains with sharp chains, it is good practice to flip the guide bar from bottom to top. Sharpening the Saw Chain WARNING Improper chain sharpening increases the potential of kickback. A springpole is any log, branch, rooted stump, or sapling which is bent under tension by other wood so that it springs back if the wood holding it is cut or removed. On a fallen tree, a rooted stump has a high potential of springing back to the upright position during the bucking cut to separate the log from the stump. Watch out for springpoles, they are dangerous. TROUBLESHOOTING Failure to replace or repair damaged chain can cause serious injury.
