CUTTING INSTRUCTIONS GENERAL [NOTE] Read the ECHO “CHAIN SAW SAFETY MANUAL” included with your chain saw for additional cutting and safety instructions. In all circumstances the operation of the chain saw is a oneman job. It is difficult at times to take care for your own safety, so don’t assume the responsibility for a helper as well. After you have learned the basic techniques of using the saw, your best aid will be your own good common sense...
FELLING A TREE CAUTION DIRECTION OF FALL A falling tree can seriously damage anything it may hit - a car, a house, a fence, a power line, or another tree. There are ways to make a tree fall where you want it, so first decide where that is! Before cutting, clear the area around the tree. You will need good footing while working and you should be able to work the saw without hitting any obstacles. Next, select a path of retreat.
Don’t cut with the saw overhead or the bar in a vertical position. If the saw should kick back you may not have good enough control to prevent possible injury. Bucking is the sawing of a log or fallen tree into smaller pieces. There are a few basic rules which apply to all bucking operations. BUCKING Uphill position Keep both hands on the handles at all times. Support logs if possible. When cutting on a slope or hillside, always stand uphill.
INFORMATION Kickback Safety Features The following features are recommended for this model as Kickback Safety Features. • Double Guard Low Kick Type Guide Bar or Asymmetrical Low Kick Type Guide Bar Note: Your saw chain can be equipped with either of these bars. Double Guard Bar Reduced nose radius NOTE Use Oregon® replacement guide bars. The following guide bars may be considered to have equivalent kickback energy.
MAINTENANCE AND CARE AIR FILTER A C • • • • Check before every use. Pull choke (A) all the way out (close position). Loosen bolt and remove air cleaner (B) cover and filter (C). Lightly brush dust off filter, and inspect for damage. AUTOMATIC OILER • B The discharge volume of the automatic oiler is adjusted to 3 to 4 cc/mm (@ 7000 rpm) prior to shipment from the factory. Always check oil discharge when in use.
SPARK PLUG • Check periodically • Gap = 0.65mm (.026 in.) • Replace if either electrode is worn, or if the insulator is fouled by oil or other deposits. • Torque = 145 – 155 kg*cm (125 – 135 in. lb.) CAUTION: Do not over-torque. COOLING SYSTEM CLEANING • Remove spark plug lead. • Remove two (2) muffler cover screws and muffler cover. • Remove four (4) recoil starter housing screws and starter housing.
Before starting the unit for adjustment, check the following items: • The correct spark plug must be clean and properly gapped. • The air filter element must be clean and properly installed. • The muffler spark arrestor screen and exhaust port must be clear of carbon. • The standard bar and chain combination (see page 4) must be installed to the power head, and properly tensioned. A 1. Start engine and run for several minutes to reach operating temperature. 2. Stop engine.

When chain has been filed on the bar, supply sufficient oil to it, rotate the chain slowly to wash away the filings before using again.
TROUBLESHOOTING Poor performance of the engine and/or cutting mechanism can normally be prevented by carefully following these instructions. Poor performance can easily be corrected even by a beginner. When the engine does not function properly check the following three (3) points first.
Improper fuel used ........................................ Use fuel with correct mixing ratio. Never use gasoline of poor quality. Table 2 Spark plug defective (worn) .......................... Replace. Engine overheated As cooling fins clogged, air does not pass well ........................................ Clean fins. Ouput (engine speed) insufficient Excessive deposits in combustion chamber ..................................... Disassemble and remove carbon.
CORRECT USE OF CHAIN BRAKE The installation of a chain brake may be mandatory by law or as stipulated by insurance regulations in your area of operation. You should inquire through local government offices, your employer or your local dealer to ensure that your chain saw conforms to the required safety standard. Echo chain brakes have been designed and tested to comply with international safety standards as follows. USA: ANSI Standard B175.
