Ryobi TR45K manual Depth of CUT, Cut, 1ST. Pass

DEPTH OF CUT

See Figure 9.

Depth of cut affects the rate of feed and the quality of a cut. Using the proper depth of cut can lessen the possibility of damage to the trimmer motor and cutter.

A deeper cut requires a slower feed than a shallow one. Mak- ing a cut that is too deep will slow the feed so that the cutter is scraping, rather than cutting, and is not recommended.

A too-deep cut can cause smaller cutters to be broken off. Cutters that are 1/16 in. (1.6 mm) in diameter are easily broken off when subjected to too much side thrust. A larger cutter is not as likely to break, but attempting a cut that is too deep may result in a rough cut, and may make it difficult to guide and control the cutter as desired.

It is recommended that you do not exceed 1/8 in. (3.2 mm) depth of cut in a single pass, regardless of the cutter size or the softness or condition of the workpiece. This will result in a higher quality cut.

To make deeper cuts, it is necessary to make as many suc- cessive passes as required, lowering the cutter 1/8 in

(3.2 mm) for each new pass. To save time, perform all the cutting necessary at one depth setting, then lower the cutter for the next pass. This will assure uniform depth when the final pass is completed.

WARNING:

If the desired depth of cut is greater than can be safely cut in one pass, make cuts in two or more passes. Do not remove more than 1/8 in. in a single pass. Excessive depth of cut can result in loss of control and the possibility of serious personal injury.
