Make sure that the engine has stopped and is cool before performing any service to the unit. Contact with any moving parts, the cutting head or a hot muffler may result in personal injury.

■REFILLING TRIMMING LINE

WARNING

For safety reasons, do not use metalreinforced line.

[BCZ3050S] [BCZ3050SW] (MA1-a)

1.For replacement line, use a diameter of

.095in (2.4mm). The spool is capable for a line up to 20feet (6m) on the 4” head. Avoid using a larger line as it may cut down the trimming performance.

2.Pinch the slotted area on the both sides of the spool housing to unhook the bottom cap.

3.Take out the spool and pull off the old line. Fold new line so that one half line is 4.7in.(12cm) shorter than another half. And then, hook bended end in the slot of the spool.

4.Wind up the line in the correct direction as indicated on the spool.

5.Hook each end of the line in the slot on the edge of the spool, and then put the

MA1-b

ends through the eyelets on the housing. Make sure that the spring and the washers are in place.

6.While holding the spool against the housing, pull the line ends to release them from the slot.

7.Line up the slot on the bottom cap with the hook on the housing, press the cap against the housing until it clicks.

NOTE

The spool is designed to hold 20 feet of

.095 or 18 feet of .105 inch monofilament line. RedMax recommends Cable Twist™ line for best performance for commercial use. RedMax Cable Twist™ line is available from your local RedMax Dealer.
