Maintenance & Care

Periodic maintenance schedule:

General recommendations:

• The warranty on this trimmer does not cover items that have been subjected to operator abuse or negligence. To receive full value from the warranty, the operator must maintain the trimmer as instructed in this manual.
• Some adjustments must be made periodically to properly maintain your trimmer
• All adjustments in the Maintenance section of this manual must be checked at least once each season.

Engine maintenance:

• Use the following maintenance section to keep your unit in good operating condition. All the maintenance information for the engine is in the "Engine Operator's Manual '. Before you start the engine, read this manual.

WARNING:

Before you inspect, clean, or service the trimmer, stop the engine. Make sure that all moving parts have stopped. Disconnect the wire from the spark plug.

HOW TO CHANGE THE OIL:

• Shut off the engine and wait for it to cool.
• Disconnect the spark plug wire from the spark plug.
• Remove the oil drain plug. (See Figure 11).
• Drain all the engine oil into a flat pan.
• Install the oil drain plug. Make sure the oil drain plug is tight.
• Remove the dipstick.
• Fill the engine crankcase. DO NOT overfill; refer to the engine preparation section for instructions on filling oil to the proper level.
• Connect the spark plug wire to the spark plug.

HOW TO REPLACE TRIMMER LINE:

• When the trimmer line becomes worn to half the original length, replace the trimmer line. For the best performance, use a heavy gauge 4 mm (0.155") trimmer line.
• Stop the engine. Wait for all moving parts to stop. Disconnect the wire from the spark plug.
• Remove the worn trimmer line from the retainer.
• Cut the length of the trimmer line to 546 mm (21.5"). Use the length guide located on the shield to make sure the trimmer line is the correct length. (See Figure 12).
• DO NOT allow the length of the lines to vary more than one inch. Make sure the trimmer head is balanced and does not vibrate.
• Thread the ends of the new trimmer line through the outside loops (see Figure 13).
• Take the ends of the line, cross over the line retainer and thread the ends through the centre hole (See Figure 14).
• Then, check to make sure that the ends af the line are even (See Figure 15).
• Follow the same steps for the line on the alternative side.

IMPORTANT To extend the life of the trimmer line, keep the trimmer line moist. If not kept moist. the nylon trimmer line will become dry and brittle. Keep extra trimmer line in a can of water. The line will then stay flexible and easy to change. A flexible line will also last much longer.
