Assembly, Mounting and Removing Guard

Assembly

: To prevent accidental operation, turn off tool and remove battery before making any adjustments or removing or installing attachments or accessories. Failure to do this could result in serious personal injury.

Attaching the Side Handle

•A three position auxiliary handle (5) is furnished with your grinder and can be screwed into either side of the grinder housing as well as into the top.

: This handle SHOULD BE USED AT ALL TIMES to maintain complete control of the tool. Always make sure the handle is tight.

Accessories

It is important to choose the correct guards, backing pads and flanges to use with grinder accessories. See pages 13 and 14 for information on choosing the correct accessories.

: Accessories must be rated for at least the speed recommended on the tool warning label. Wheels and other accessories running over their rated accessory speed may fly apart and cause injury. Threaded accessories must have a 5/8 inch-11 hub. Every unthreaded accessory must have a 7/8 inch (22mm) arbor hole. If it does not, it may have been designed for a circular saw. Use only the accessories shown on pages 13 and 14 of this manual. Accessory ratings must always be above tool speed as shown on tool nameplate.

Mounting Guard

MOUNTING AND REMOVING GUARD

: Turn off tool and remove battery before making any adjustments or

removing or installing attachments or accessories.

: Guards must be used with all grinding wheels, sanding flap discs,

wire brushes, cut-off wheels and wire wheels. The tool may be used without a guard only when sanding with conventional sanding discs. Porter Cable model PC1800AG is provided with a guard intended for use with depressed center wheels (Type 27) and hubbed grinding wheels (Type 27). The same guard is designed for use with sanding flap discs (Type 27 and 29) and wire cup brushes. Grinding and cutting with wheels other than Type 27 and 29 require different accessory guards included with tool. A Type 1 guard is provided for use with a Type 1 wheel and is shown in figures E and F below.

Both Type 27 and Type 1 guards attach and are removed in the same way as described below.

1.Figure E ATTACHING - Open the guard latch (10), and align the lugs on the guard (9) with the slots on the gear case cover.

2.Push the guard down until the guard lugs engage and rotate freely in the groove on the gear case hub.

3.With the guard latch open, rotate the guard (9) into the desired working position. The guard body should be positioned between the spindle and the operator to provide maximum operator protection.
