UK - Page 16 PREPARING FOR CUTTING PROPER GRIP ON HANDLES See Figures 20 and 21. Refer to “Specific Safety Rules – Safety Apparel” earlier in this manual for appropriate safety equipment. Wear non-slip gloves for maximum grip and protection.
UK - Page 17 BASIC OPERATING/CUTTING PROCEDURES Practise cutting a few small logs, using the following technique to get the “feel” of using the saw before you begin a major sawing operation. 1. T ake the proper stance in front of the wood with the saw idling.
UK - Page 18 W ARNING: Weather conditions and altitude may affect carburation. Do not allow bystanders close to the chainsaw while adjusting the carburettor. ADJUSTING IDLING SPEED If the engine starts, runs, and accelerates but will not idle, turn the idling speed screw “ T ” clockwise to increase idling speed.
UK - Page 19 FELLING TREES HAZARDOUS CONDITIONS See Figure 29. OPERA TION W ARNING: Do NOT fell trees near power lines or near buildings which could be struck by falling limbs or the tree itself.
UK - Page 20 PROPER PROCEDURE FOR TREE FELLING See Figure 30. 1. Pick your escape route (or routes in case the intended route is blocked). Clear the immediate area round the tree and make sure there are no obstructions in your planned path of retreat.
UK - Page 21 3. Cut a notch about one-third the diameter of the trunk in the side of the tree. Make the notch cuts so they intersect at right angles to the line of fall. This notch should be cleaned out to leave a straight line. To keep the weight of the wood off the saw, always make the lower cut of the notch before the upper cut.
UK - Page 22 REMOVING BUTTRESS ROOTS A buttress root is a large root extending from the trunk of the tree above the ground. Remove large buttress roots before felling. Make the horizontal cut into the buttress first, f ollow ed by the v er tical cut. Remove the resulting loose section from the work area.
UK - Page 23 BUCKING LOGS UNDER STRESS Make the first bucking cut one-third of the way through the log and finish with a two-thirds cut on the opposite side. As you cut the log, it will tend to bend. The sa w can become pinched or hung in the log if you make the first cut deeper than one-third of the diameter of the log.
UK - Page 24 LIMBING AND PRUNING See Figure 39. Work slowly, keeping both hands on the saw with a firm grip. Maintain secure footing and balance. Keep the tree between you and the chain while limbing. Cut from the side of the tree opposite the branch you are cutting.
UK - Page 25 ASSEMBLING THE BAR AND CHAIN DANGER: Never start the engine before installing the guide bar, chain, drive case cover, and clutch drum. Without all these parts in place, the clutch may fly off or explode, exposing the user to possible serious injury.
UK - Page 26 6. Lay out the saw chain in a loop and straighten any kinks. The cutters should face in the direction of chain rotation. If the y f ace back wards, turn the loop ov er . See Figure 45 . 7. Place the chain drive links into the bar groove. See Figure 46.
UK - Page 27 11. Replace the outer guide bar plate, ensuring that the bar pin groove is at the bottom with the upper and lower edges angled away from the guide bar. 12. Replace the clutch cover and bar mounting nuts. 13. Tighten the bar mounting nuts finger tight only.
UK - Page 28 ADJUSTING THE CHAIN TENSION See Figures 52, 53 and 54. W ARNING: Never touch or adjust the chain while the motor is running. The saw chain is very sharp. Always wear protective gloves when performing maintenance on the chain. 1. Stop the engine before setting the chain tension.
UK - Page 29 Fig. 55 Fig. 56 RAKER CLEARANCE INSPECT DRIVE SPROCKET CUTTING CORNER SIDE PLATE DEPTH GAUGE TOE GULLET HEEL RIVET HOLE TOP PLATE SHARPENING THE CUTTERS See Figures 57 to 62. Be careful to file all cutters to the specified angles and to the same length, as fast cutting can only be obtained when all cutters are uniform.
UK - Page 30 Fig. 60 Fig. 61 Fig. 59 CHECK FOR WEAR OR DAMAGE LEFT-HAND CUTTERS RIGHT-HAND CUTTERS Fig. 62 CAUTION: A dull or improperly sharpened chain can cause excessive engine speed during cutting which may result in severe engine damage. W ARNING: Improper chain sharpening increases the potential of kick-back.
UK - Page 31 TOP PLATE FILING ANGLE CORRECT 30° – file holders are marked with guide marks to align file properly to produce correct top plate angle. LESS THAN 30° – for cross cutting. MORE THAN 30° – feathered edge dulls quickly.
UK - Page 32 RESTORE ORIGINAL SHAPE BY ROUNDING THE FRONT Fig. 68 LUBRICATING HOLE Fig. 67 MAINTAINING THE GUIDE BAR See Figure 68. MAINTAINING THE SAFE-T-TIP NOSE GUARD See Figures 69 and 70. MOUNTING SCREW SAFE-T-TIP Fig. 69 MAINTENANCE Every week of use, reverse the guide bar on the saw to distribute the wear for maximum bar life.
UK - Page 33 MOUNTING THE SAFE-T-TIP® NOSE GUARD See Figures 69 and 70. 1. Mount the SAFE-T-TIP on the bar nose. 2. Fit the locking rivet or tab in the recessed hole in the guide bar. 3. Tighten the screw with your finger. 4. From the finger tight position, tighten the screw an additional three-quarters of a turn using a spanner.
UK - Page 34 CLEANING THE ENGINE Clean the cylinder fins and flywheel fins with compressed air or a brush periodically. Dangerous overheating of the engine may occur due to impurities on the cylinder. W ARNING Never run the saw without all the parts, including the drive case cover and starter housing, securely in place.
