Align the chain tensioning pin with the hole in the guide bar. See Figure 17. WARNING! Never attempt to install, replace, or adjust the chain with the engine running. WARNING! The saw chain is very sharp. Wear gloves to protect your hands when handling.
Adjusting the Chain 3. Lift the nose of the guide bar while turning the chain tensioning screw. See Figure 20. WARNING! Never attempt to install, replace, or adjust the chain with the eingine running. WARNING! The saw chain is very sharp. Wear gloves to protect your hands when handling. Clockwise to tighten the chain CAUTION! Counterclockwise to loosen the chain. A loose chain can jump off the guide bar causing damage to the chain and associated equipment.
Chain Oiler Adjusting Oil Flow Rate CAUTION! WARNING! Never fill the oil reservoir nor adjust the oiler with the engine running. IMPORTANT! The service life of the chain and guide bar is affected by the chain and guide lubricant. Using superior lubricant such as genuine Bar and Chain Oil will help ensure a long service life, For cold weather operation, mix bar and chain oil with an equal part of kerosene.
Cutting above obstacles: Thanks to the unit's long reach it is possible to prune branches that are overhanging obstacles, such as rivers or lakes. The tool angle in this case depends on the position of the branch. Typical applications Standard cut: The most convenient working position is a tool angle of 60°, but any other angle may be used to suit the situation concerned.
Working techniques Flush-cutting thick branches: If branch diameter is more than 10cm ( 4 ”) , first perform undercut (3) and cross - cut at a distance ( A ) of about 25cm ( 10 ”) from the final cut . Then carry out the flush cut (4), starting with a relieving cut and finishing with a cross - cut .
50-hour Maintenance Every 50 hours of operation (more frequently in dusty or dirty conditions): Remove and clean the cylinder cover and clean dirt and debris from the cylinder cooling fins. Remove the sprocket cover and inspect the sprocket for excessive dirt,debris,or wear, Remove the guide bar and clean out the guide bar groove.If the sprocket is excessively worn, replace it with a new one.See Figure 36. Figure 36 Old grease being purged from the gearcase, which can be seen in the outer tube cavity.
Sharpening the Chain When the cutting edges of the blade become dull, they can be re-sharpened with a few strokes of a file. In order to keep the blade in balance, all cutting edges must be sharpened equally. In addition, inspect the chain for correct adjustment (more frequently with a new chain). The chain should feel snug but still pull freely. See Figure 40. Sharpening Instructions (Fig.
Correct Filing Technique Correct angle on top plate Silghtly protruding hook or point (curve on non-chisel chain) Top of depth gauge at correct height below top plate Front of depth gauge rounded Filling Problems Top plate angle less than recommended Hook in side plate cutting edge High depth gauge Top plate angle more than recommended Cause File held at less than recommended angle. Result slow cutting. Requires extra effort to cut. Remedy File cutters to recommended angle.
