Grizzly G9907, Instruction Manual

G9907 Triangular Sander

OPERATION INSTRUCTIONS

Getting Started

After making sure the power source

matches the specifications on the sander

label, plug in sander. Push the black

switch (on top of the tool’s handle) forward

to turn it on, and pull the switch back to

turn the sander off. When you first turn it

on, make sure that your finger remains on

the switch so you can STOP the sander in

case there’s a problem. The sander

should run smoothly. Strange or unnatural

noises should be investigated and correct-

ed before operating the machine further. 

If you cannot easily locate the source of

an unusual noise or vibration, contact our

service department for help.

Selecting Abrasives

The best results from your G9907

Triangular Sander will be accomplished

using the proper grit of coated abrasive.

As a rule, you will want to start with a more

coarse paper for removing large defects or

rough spots, then work through finer grits

one or two grades at a time until you

achieve the smoothness and quality you

desire. 

Any time you are unsure about which grit

to begin with, experiment in a small corner

or area that isn’t very noticeable on your

project. Ideally, you want to achieve the

balance of removing defects without dam-

aging your work.

ALUMINUM OXIDE and SILICON CAR-

BIDE abrasives are an excellent choice

because they last longer and are sharper

than natural abrasives.

Attaching Abrasives

Abrasive sheets are easily attached with

the hook-and-loop system on the pad of

your G9907 sander. Fit the sheet over the

pad so that it covers the entire area, push

and slightly twist to make sure the coated

abrasive sheet is snug on the pad. Make

sure you don’t cover the suction holes.

Remove abrasive sheets by pinching an

edge or corner and peeling off. 

Using the Sander

Starting with the coarsest grit you have

determined to be sufficient for the job,

sand the work evenly, in the same direc-

tion as the grain of the wood. Always keep

the machine moving so the finish of your

work stays consistent. If you stay in one

place too long, then the sander may pro-

duce a depression in the wood that will

compromise your finish. 

Sanding across the grain of the wood may

be necessary in some cases to remove

rough defects. This should be done with

caution however, because it can produce

cross-grain scratching that will require fur-

ther sanding to remove.

Change abrasive sheets as soon as the

grit becomes dull. You will recognize this

when the sander seems to slide across the

work without any “bite.”

Never apply excessive force while sand-

ing. Your sander will last longer if you let

“it” do the work. Using a slight pressure

barely greater than the weight of the

machine is ideal because you can still

maintain control while obtaining a fine fin-

ish.
