EN POW64115 GASOLINE CHAINSAW 37.2CC 16” POW64115 1 APPLIANCE These models are intended for infrequent use by homeowners, cottagers, and campers, and for such general applications as clearing, pruning, cutting firewood, etc. They are not intended for prolonged use. If the intended use involves prolonged periods of operation, this may cause circulatory problems in the user’s hands due to vibration. It is not designed for commercial use.

EN POW64115 WARNING! When using gas tools, basic safety precautions, including the following, should always be followed to reduce the risk of serious personal injury and/or damage to the unit. 3 PACKAGE CONTENT LIST     Remove all packing materials Remove remaining packaging and transit supports (if existing) Check the completeness of the packing content Check the appliance, the power cord, the power plug and all accessories for transportation damages.
PAGE 5
POW64115 EN  Use caution when handling fuel. To avoid fire, move the chain saw at least 10 feet (3m) from the fueling point before starting the engine.  DO NOT allow other persons to be near when starting or cutting with the chain saw. Keep bystanders and animals out of the work area.  DO NOT start cutting until you have a clear work area, secure footing, and a planned retreat path from the falling tree.  Keep all parts of your body away from the saw chain when the engine is running.

POW64115 6 EN KICKBACK SAFETY PRECAUTIONS KICKBACK may occur when the NOSE or TIP of the guide bar touches an object, or when wood closes in and pinches the saw chain in the cut. Tip contact in some cases may cause a lightning-fast reverse reaction, kicking the guide bar up and back toward the operator. PINCHING the saw chain along the BOTTOM of the guide bar may PULL the saw forward away from the operator.

PAGE 8
POW64115 EN  Make sure the chain brake lever is pulled back into the disengaged position(fig. 3b) fig 3b C  Remove the bar retaining nut(s) (B). Remove the chain brake cover (C) by pulling straight out, some force may be required. (fig. 3c). B fig 3c  Place the slotted end of the guide bar over the bar bolt (F). Slide guide bar behind clutch drum (G) until the guide bar stops (fig. 3d). fig 3d 7.3.
PAGE 9
POW64115 EN Note: the saw chain may droop slightly on the lower part of bar. This is normal.  Pull guide bar forward until chain is snug. Ensure all drive links are in the bar groove.  Install the clutch cover making sure the tang is positioned in the lower hole in the guide bar. Make sure the chain does not slip off of the bar. Install the bar retaining nut hand tight and follow tension adjustment instructions in section saw chain tension adjustment.
PAGE 11
POW64115 EN Caution: if saw chain is too loose or too tight, the sprocket, bar, chain, and crankshaft bearings will wear more rapidly. Study fig.6 for information concerning correct cold tension (A), correct warm tension (B), and as a guide for when saw chain needs adjustment (C). 7.3.5 Chain brake mechanical test Your chain saw is equipped with a chain brake that reduces possibility of injury due to kickback.

EN POW64115 9.6 Chain brake operational test Test the chain brake periodically to ensure proper function. Perform a chain brake test prior to initial cutting, following extensive cutting, and definitely following any chain brake service. Test chain brake as follows:  Place saw on a clear, firm, flat surface.  Start engine.  Grasp the rear handle (A) with your right hand (fig. 10).  With your left hand, hold the front handle (B) [not chain brake lever (C)] firmly (fig. 10).

POW64115 EN  To adjust the oil flow, turn the adjusting screw at the bottom side of the housing (19)  Turning it clockwise reduces the oil flow, while turning it counterclockwise increases the oil. 19 9.9 9.9.1 General cutting instructions Felling Felling is the term for cutting down a tree. Small trees up to 6-7 inches (15-18cm) in diameter are usually cut in a single cut. Larger trees require notch cuts. Notch cuts determine the direction the tree will fall.
PAGE 18
POW64115 EN WARNING: Never walk in front of a tree that has been notched. Make the felling cut (D) from the other side of the tree and 1.5 2.0 inches (3-5 cm) above the edge of the notch (C) (Fig. 11b) fig 11b Never saw completely through the trunk. Always leave a hinge. The hinge guides the tree. If the trunk is completely cut through, control over the felling direction is lost. Insert a wedge or felling lever in the cut well before the tree becomes unstable and starts to move.
PAGE 19
POW64115 9.9.3 EN Bucking Bucking is cutting a fallen log into lengths. Make sure you have a good footing and stand uphill of the log when cutting on sloping ground. If possible, the log should be supported so that the end to be cut off is not resting on the ground. If the log is supported at both ends and you must cut in the middle, make a downward cut halfway through the log and then make the undercut. This will prevent the log from pinching the bar and chain.

10 EN POW64115 MAINTENANCE INSTRUCTIONS All chain saw service, other than items listed here in your user manual maintenance instructions, should be performed by a professional. 10.1 Preventive maintenance A good preventive maintenance program of regular inspection and care will increase life and improve performance of your chain saw. This maintenance checklist is a guide for such a program.

EN POW64115  Lift the air filter out of air-box (fig. 15b).  Clean air filter with compressed air. When heavily polluted, wash filter in clean, warm, soapy water. Rinse in clear, cool water. Air dry completely. fig 15b Note: it is advisable to have a supply of spare filters.  Install air filter. Install engine / air filter cover. Make sure latch (E) latch (F) and cover fit properly. Tighten the cover retaining knob securely.
PAGE 22
POW64115 10.5 EN Spark plug Note: for efficient operation of saw engine, spark plug must be kept clean and properly gapped. B A  Push stop switch down.  Remove knob (A) holding air filter cover in place; remove the top cover (B) by loosening the cover retaining screw. Cover will lift off. (fig. 18a) fig 18a  Disconnect the wire connector (C) from the spark plug (D) by pulling and twisting at the same time (fig. 18b).  Remove spark plug with spark plug socket wrench.
PAGE 23
POW64115 EN Tools for lubrication: The lube gun (optional) is recommended for applying grease to the guide bar sprocket tip. The lube gun is equipped with a needle nose tip which is necessary for the efficient application of grease to the sprocket tip. To lubricate sprocket tip: Warning: wear heavy duty work gloves when handling the bar and chain.  Press the stop switch down. Note: it is not necessary to remove the saw chain to lubricate the guide bar sprocket tip. Lubrication can be done on the job.
PAGE 24
EN POW64115  To gain well shaped sawdust particles, use sharp chain. If there appears wooden powder, you must sharpen the saw chain. Warning: all cutting teeth must be similarly long. Different length of the teeth can cause rough run of the chain or its rupture, as well.  Minimum length of the teeth must be 4mm. If they are shorter, remove the saw chain.  Angles, which the teeth are under, must be followed.  To sharpen the chain basically, make 2 to 3 pulls of the file from the inside out.
PAGE 25
POW64115 EN 11.4 Guide bar The bar should be reversed every 8 working hours to ensure uniform wear. Keep the bar groove and lubrication hole clean using a bar groove cleaner (optional). (fig. 24) check the bar rails frequently for wear and, if necessary, fig 24 Warning: never mount a new chain on a worn sprocket or self-aligning ring. Bar wear - turn guide bar frequently at regular intervals (for example, after 8 hours of use), to ensure even wear on top and bottom of bar.
