manual abstract
•Reduce the risk of the saw chain breaking or jumping off the bar. •Obtain optimal cutting performance. •Extend the life of cutting equipment. •Avoid increasing vibration levels. General rules •Only use cutting equipment recommended by us! See instructions under the heading Technical data. •Keep the chain’s cutting teeth properly sharpened! Follow our instructions and use the recommended file gauge. A damaged or badly sharpened chain increases the risk of accidents. •Maintain the correct depth gauge setting! Follow our instructions and use the recommended depth gauge clearance. Too large a clearance increases the risk of kickback. •Keep the chain properly tensioned! If the chain is slack it is more likely to jump off and lead to increased wear on the bar, chain and drive sprocket. •Keep cutting equipment well lubricated and properly maintained! A poorly lubricated chain is more likely to break and lead to increased wear on the bar, chain and drive sprocket. Cutting equipment designed to reduce kickback WARNING! Faulty cutting equipment or the wrong combination of bar and saw chain increases the risk of kickback! Only use the bar/saw chain combinations we recommend, and follow the filing instructions. See instructions under the heading Technical data. The only way to avoid kickback is to make sure that the kickback zone of the bar never touches anything. By using cutting equipment with ”built-in” kickback reduction and keeping the chain sharp and well- maintained you can reduce the effects of kickback. Bar The smaller the tip radius the lower the chance of kickback. Chain A chain is made up of a number of links, which are available in standard and low-kickback versions. IMPORTANT! No saw chain design eliminates the danger of kickback. WARNING! Any contact with a rotating saw chain can cause extremely serious injuries. Some terms that describe the bar and chain To maintain the safety features of the cutting equipment, you should replace a worn or damaged bar or chain with a bar and chain combinations recommended by RedMax. See instructions under the heading Technical Data for a list of replacement bar and chain combinations we recommend. Bar •Length (inches/cm) •Number of teeth on bar tip sprocket (T). •Chain pitch (inches). The spacing between the drive links of the chain must match the spacing of the teeth on the bar tip sprocket and drive sprocket. •Number of drive links. The number of drive links is determined by the length of the bar, the chain pitch and the number of teeth on the bar tip sprocket. •Bar groove width (inches/mm). The groove in the bar must match the width of the chain drive links. •Chain oil hole and hole for chain tensioner. The bar must be matched to the chain saw design. Chain •Chain pitch (inches) •Drive link width (mm/inches) •Number of drive links. Maintenance of saw chain and guide bar Chain WARNING! Keep the chain’s cutting teeth properly sharpened! Follow our instructions and use the recommended file gauge. A damaged or badly sharpened chain increases the risk of accidents. The cutting teeth need to be sharpened when: •Sawdust becomes powder-like •You need extra force to saw in •The cut way does not go straight •Vibration increases •Fuel consumpion increases Sharpening cutting teeth Important Always wear gloves, when working with the chain, in order to protect your hands from injury. Make sure the saw chain is held securely, before filing! •Place your flle on the cutting teeth and push straight forward. Keep the flle position as illustrated. 1525°10° WARNING! Departure from the sharpening instructions considerably increases the risk of kickback. Use a round file of proper size for your chain. Chain type 72 LPX File size 7/32” /5,5mm After every cutting tooth has been set, check the depth gauge and flle it to the proper level as illustrated. 1Appropriate gauge checker 2Make the shoulder round 3Depth gauge standard WARNING! The risk of kickback is increased if the depth gauge setting is too large! Make sure every cutting tooth has the same lenght and egde angels as illustrated. 1Cutting teeth lenght 2Filing angle 3Side plate angle 4Top plate cutting angle When the length of the cutting teeth has worn down to only 5/32 inch (4 mm) the chain must be replaced. Bar Reverse the bar occasionally to prevent partial wear. The bar rail should always be square. Check for wear of the bar rail. Tensioning the chain WARNING! A slack chain may jump off the bar and cause serious or even fatal injury. The more you use a chain the longer it becomes. It is therefore important to adjust the chain regularly to take up the slack. Check the chain tension every time you refuel. NOTE! A new chain has a running-in period during which you should check the tension more frequently. Tension the chain as tightly as possible, but not so tight that you cannot pull it round freely by hand. •Loosen the bar nuts that hold the clutch cover/chain brake. Use the combination spanner. Then tighten the bar nuts by hand as...
