9 ADJUSTMENTS

9.12 BEDKNIFE ADJUSTMENT __________________________________________________

Read

Section 9.11

before making the adjustment.

Start adjustment at the leading end of the reel,
followed by the trailing end.

The leading end of the

reel blades is that end which passes over the
bedknife first during normal reel rotation.

Use adjusters

and

, to adjust gap. Rotate

adjusters (Clockwise) to close gap. Each click of the
adjuster moves the bedknife 0.001” (0.025 mm)
closer to the reel.

Slide a feeler gauge or shim stock 0.001” - 0.003”
(0.025 - 0.075 mm) between the reel blade and
the bedknife. Do not turn the reel.

Adjust the trailing end of the reel to the same
gap in a similar manner then recheck the
adjustment at the leading end.

When the reel is properly adjusted to the
bedknife, the reel will spin freely and you should
be able to cut a piece of newspaper, along the
full length of the reel, when the paper is held at
90° to the bedknife.
