WARNING:
Gasoline is highly flammable, and its vapors can explode if ignited. Take the following precautions:
WARNING:
Kickback may occur when the nose or tip of the guide bar touches an object, or when the wood closes in and pinches the saw chain in the cut. Tip contact in some cases may cause a lightning-fast reverse action, kicking the guide bar rapidly back towards the operator. Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back towards the operator. Either of these reactions may cause you to lose control of the saw, which could result in serious injury to the user.
Do not rely exclusively upon the safety devices built into your saw. As a pole saw user, you should take several steps to keep your cutting jobs free from accident or injury.
RULES FOR SAFE OPERATION
• Do not wear loose clothing or jewelry, as they can get caught in moving parts. Non-skid footwear is recommended when working outdoors. Wear protective hair covering to contain long hair.
• Use safety glasses, safety footwear, snug fitting clothing, protective gloves, and protective hearing and head gear.
• Use caution when handling fuel. Move the pole saw at lest 30 feet (9.1 m) from the fueling point before starting the engine.
• Keep the work area clean. Cluttered areas invite injuries. Do not start cutting until you have a clear work area, secure footing, and a planned retreat path from the falling branches.
• Stay Alert. Watch what you are doing. Use common sense. Do not operate the pole saw when you are tired. Keep all parts of your body away from the saw chain when the motor is operating. Before you start the saw, make sure the saw chain is not contacting anything.
• Disconnect the pole saw when not in use, before servicing, and when changing accessories and attachments such as saw chain and guard.
• Check damaged parts. Before further use of the pole saw, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting, and any other conditions that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced by an authorized service center, unless otherwise indicated in this instruction manual.
• Use extreme caution when cutting small sized brush and sapling, as slender material may catch the saw chain and be whipped toward you or pull you off balance.
• Do not operate a pole saw in a tree unless you are specifically trained to do so. When cutting a limb that is under tension, be alert for spring back so that you will not be struck when the tension in the wood fibers is released.
• Do not expose the pole saw to rain. Do not use the pole saw in damp or wet locations.
• Do not use the pole saw in the presence of flammable liquids or gases.
• All pole saw service, other than the items listed in the user manual safety and maintenance instructions, should be performed by competent pole saw personnel. Do not attempt to repair it yourself; there are no user serviceable parts inside.
• The pole saw will do a better and safer job when used at the rate for which it was intended.
• Use the right tool. Cut wood only. Do not use the pole saw for purposes for which it was not intended. For example, do not use the pole saw for cutting plastic, masonry, or non-building materials.
• Use devices, such as low-kickback chain, guide bar nose guards, chain brakes and special guide bars, which reduce the risks associated with kickback.
• There are no other replacement components for achieving kickback protection in accordance with CSA Z62.3.
• Do not operate a pole saw that is damaged, improperly adjusted, or not completely and securely assembled. Be sure that the saw chain stops moving when the trigger is released.

2. Move two to four inches farther out on the limb. Make the second cut from above the limb. Continue the cut until you cut the limb off.
3. Make the third cut as close to the tree trunk as possible on underside of limb stub. Use the top of the guide bar to make this cut. Cut a third through the diameter of stub.
4. Make the fourth cut directly above the third cut. Cut down to meet the third cut. This will remove the limb stub.
OPERATING INSTRUCTIONS
WARNING:
Kickback may occur when the nose or tip of the guide bar touches an object, or when the wood closes in and pinches the saw chain in the cut. Tip contact in some cases may cause a lightning-fast reverse action, kicking the guide bar rapidly back towards the operator. Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back towards the operator. Either of these reactions may cause you to lose control of the saw, which could result in serious injury to the user.
Do not rely exclusively upon the safety devices built into your saw. As a chain saw user, you should take several steps to keep your cutting jobs free from accident or injury.
WARNING:
If the oil tank runs out, the oil ajustment screw hole becomes clogged, or the chain fails to get proper lubrication in any fashion, the chain will overheat and cause irreversible damage to the unit and may result in severe injury. Excessive heat from friction can lead the chain to catastrophically fail and come off the bar while operating.
SAW CHAIN REPLACEMENT/INSTALLATION
1. Using a straight screwdriver turn tension adjustment screw counterclockwise (Fig. 8, A) 4 turns.
2. Remove the bar retaining nuts and screw. Then take off the chain guard (Fig. 8, B).

SAW CHAIN TENSION ADJUSTMENT
Proper tension of the saw chain is extremely important and must be checked before starting, as well as during, any cutting operation. Taking the time to make needed adjustments to the saw chain will result in improved cutting performance and prolonged chain life.
NOTE: A new chain and bar will need readjustment after as few
as 5 cuts. This is normal during the break-in period, and the interval between future adjustments will lengthen quickly (Fig. 11).

To adjust the saw chain tension:
1. Loosen the bar retaining nuts so they are hand tight (Fig. 8, B).
2. Holding the nose of the bar up, use the screwdriver to turn the guide bar adjustment screw clockwise to tighten the chain (Fig. 8, A). Turning the screw counterclockwise loosens the chain on the guide bar.
3. While wearing heavy duty work gloves (after you’ve made the adjustment), move the saw chain back and forth on the guide bar to be sure the chain moves freely and is in proper mesh with the sprocket. Never move the chain with your bare hands.
NOTE: If the chain is difficult to rotate or if it binds on the guide
bar, there is too much tension applied and it must be adjusted. To decrease tension, turn the adjustment screw counterclockwise, slowly. Move the chain back and forth until it moves freely.
4. Holding the nose in upper position, securely tighten the bar retaining nuts.
MAINTENANCE AND REPAIR INSTRUCTIONS
WARNING:
Whenever handling the saw chain, always wear work gloves for protection against sharp cutting edges.
CAUTION:
If a chain is too loose or too tight, the bar chain and saw bearings will wear more rapidly. Refer to Figure 11 for information concerning correct cold tension (A), correct warm tension (B), and a chain in need of adjustment (C).
6. Adjust the tension adjustment screw (Fig. 8, A) to allow insertion of the bar (Fig. 10). Make sure the chain follows the slot in the guide bar and adjust the tension adjustment screw to make the chain fit snugly on the underside of the bar.
7. Install the chain guard and tighten bar retaining nuts and screw (Fig. 8, B).
OILING THE CHAIN
The pole saw chain is self-lubricating. Oil is dispersed onto the chain as the unit is used. Keep an adequate amount of oil in the oil tank. Use the bar-chain oil provided in the hardware pack. Always use bar-chain and sprocket oil or similar chain saw oil.
Setting the Oil Adjustment Screw
The Oil Adjustment Screw is located on top of the gearbox assembly (Fig. 12).
1. Insert a 3/32-inch Allen wrench into the oil adjustment screw.
2. Turn the screw counterclockwise to increase oil flow to the chain, or
3. Turn the screw clockwise to restrict the oil flow to the chain.
GUIDE BAR MAINTENANCE
NOTE: Proper maintenance of the guide bar is essential to the
performance of your pole saw. Proper guide bar maintenance will keep your saw in good working order.
Most guide bar problems can be prevented merely by keeping the chain saw well maintained.
Incorrect filing and non-uniform cutter and depth gauge settings cause most guide bar problems, primarily resulting in uneven bar wear. As the bar wears unevenly, the rails widen, which may cause chain clatter and difficulty in making straight cuts.
Insufficient guide bar lubrication and operating the saw with a chain that is too tight will contribute to rapid bar wear. Refer to Saw Chain Tension Adjustment and Oiling the Chain.
To help minimize bar wear, the following guide bar maintenance is recommended:
Bar Wear
Turn guide bar frequently at regular intervals (for example, after 5 hours of use), to ensure even wear on top and bottom of bar.
Bar Grooves
Bar grooves (or rails which support and carry the chain) should be cleaned if the saw has been heavily used or if the saw chain appears dirty. Rails should always be cleaned every time the saw chain is removed.
To clean guide bar rails:
1. Remove chain guard, bar, and chain. Refer to Saw Chain Replacement / Installation.
2. Using a screwdriver, putty knife, wire brush or other similar instrument, clear residue from the rails on the guide bar (Fig. 13).
This will keep the oil passages open to provide proper lubrication to the bar and chain.
3. Ensure the sprocket in the bar turns freely during cleaning.
4. Reinstall the bar, chain, chainguard, screw, and bar retaining nuts. Refer to Saw Chain Replacement / Installation.
Oil Passages
Oil passages at the bar pad should be cleaned to ensure proper lubrication of the bar and chain during operation. This can be done using a soft wire small enough to insert into the oil discharge hole.
MAINTENANCE AND REPAIR INSTRUCTIONS
WARNING:
Ensure that the unit is off and the spark plug is disconnected (gas powerheads) before performing any maintenance on your saw.

WARNING:
If the oil tank runs out, the oil ajustment screw hole becomes clogged, or the chain fails to get proper lubrication in any fashion, the chain will overheat and cause irreversible damage to the unit and may result in severe injury. Excessive heat from friction can lead the chain to catastrophically fail and come off the bar while operating.
CHAIN MAINTENANCE
A low-kickback saw chain should always be used in conjunction with other kickback protection devices such as the hand guard, which is furnished with your unit.
Always use a replacement saw chain designed as “low-kickback” or a saw chain which meets the low-kickback performance.
A standard saw chain (a chain which does not have the kickback reducing guard links) should only be used by an experienced professional chain saw operator.
Low-Kickback Saw Chain
A low-kickback saw chain is a chain which has met the kickback performance requirements of ANSI B175.1. Do not use other replacement chain unless it has met these requirements for your specific model.
By keeping the saw chain in good working condition and correctly serviced as recommended in this manual, you will be able to maintain the safety system of your polesaw over the life of the product.
Chain Tension
Check the chain tension frequently and adjust as often as necessary to keep the chain snug on the bar, but loose enough to be pulled around by hand. Refer to Saw Chain Tension Adjustment.
Breaking in a New Saw Chain
A new chain and bar will need readjustment after as few as 5 cuts. This is normal during the break-in period, and the interval between future adjustments will begin to lengthen quickly.
Over a period of time, however, the moving parts of the saw chain will become worn, resulting in what is called chain stretch. This is normal. When it is no longer possible to obtain correct chain tension adjustment, a link will have to be removed to shorten the chain. See your MTD Authorized Service Center to have this repair performed.
CLEANING AND STORAGE
• Slacken the chain if you have retensioned it at operating temperature during cutting work.
• The chain contracts as it cools down. If it is not slackened, it may damage the gearbox and bearings.
Storing the Machine for a Short Period
Wait for the engine to cool down. Drain the fuel tank and store the machine in a dry place well away from sources of ignition until you need it again.
• Attach the transport guard to the bar/chain before storing the unit.
• Store the unit in a dry, high and/or locked location, out of the reach of children and other unauthorized persons.
Long-Term Storage
• Remove the saw chain and guide bar, clean them, and spray them with corrosion inhibiting oil.

MAINTENANCE AND REPAIR INSTRUCTIONS
SPECIFICATIONS
WARNING:
Unless you have experience and specialized training for dealing with kickback (see Important Safety Instructions), always use a low­kickback saw chain, which significantly reduces the danger of kickback. Low-kickback saw chain does not completely eliminate kickback. A low-kickback or “safety chain,” should never be regarded as total protection against injury.
WARNING:
Never remove, modify or make inoperative any safety device furnished with your unit. The hand guard and low-kickback saw chain are major safety features provided for your protection.
WARNING:
Never use a loop of chain that has more than 3 links removed from it. This could damage the sprocket.
WARNING:
Ensure that the unit is off and the spark plug is disconnected (for gas powerheads) when working on the saw chain. Wear heavy duty gloves too.
