ASSEMBLY INSTRUCTIONS

On some units, the D-handle may be pre-installed, requiring only
loosening screws and some adjustment. If this is the case, go to
step 4.

INSTALLING AND ADJUSTING THE D-HANDLE

Remove the screws and bottom clamp piece that were
installed on the D-handle for shipping.

Place D-handle the over the shaft housing and onto the
bottom clamp (Fig. 1). Place it a minimum of 6 inches
(15.24 cm) from the end of the shaft grip.

Start screws with a large Flat-head or T-25 Torx screwdriver.
Do not tighten until you make the handle adjustment.

If the D-handle was pre-installed, loosen the screws on the
handle just enough to move it.

While holding the unit in the operating position (Fig. 2),
position the D-handle to the location that provides you the
best grip.

Tighten the clamp screws evenly, until the D-handle is
secure.

INSTALLING THE CUTTING ATTACHMENT SHIELD

Use the following instructions if the cutting attachment shield on
your unit is not installed or if you ever need to re-install it.
1.

Slide the cutting attachment shield into the shield mount on
the cutting attachment. Align the screw holes in the shield
with the holes in the cutting attachment (Fig. 3).

Place a hex lock nut into one of the three recessed holes
on the top of the cutting attachment shield (Fig 4).

Install a screw into the hole from the bottom of the cutting
attachment shield and screw it into the nut installed in step
2 (Fig 5). Do not tighten.

Repeat steps 2 and 3 until all three screws have been
started, then tighten securely.
