Clean Up

Site Considerations

The unpainted surfaces are coated with a waxy

oil to prevent corrosion during shipment. Remove

this protective coating with a solvent cleaner or

citrus-based degreaser such as Grizzly’s G7895

Citrus Degreaser. To clean thoroughly, some parts

must be removed. For optimum performance

from your machine, clean all moving parts or

sliding contact surfaces. Avoid chlorine-based

solvents, such as acetone or brake parts cleaner

that may damage painted surfaces. Always follow

the manufacturer’s instructions when using any

type of cleaning product.

Placement Location

Consider existing and anticipated needs, size of

material to be processed through each machine,

and space for auxiliary stands, work tables or

other machinery when establishing a location for

your new combo sander.

We recommend placing the machine at the corner

of a benchtop so that both the sanding belt and

disc can be accessed without having to move the

sander.

See Figure 5 for the minimum working

clearances.

Gasoline and petroleum

products have low flash

points and can explode

or cause fire if used to

clean machinery. DO

NOT use these products

to clean the machinery.

��^��

�

��^��

�

Many cleaning solvents

are toxic if inhaled.

Minimize your risk by only

using these products in a

well ventilated area.

Figure 5. Model H8192 placement dimensions.

G7895—Grizzly Citrus Degreaser

This natural, citrus-based degreaser is a great

solution for removing export grease, and it’s much

safer to work around than nasty solvents.

Children and visitors may

be seriously injured if

unsupervised around this

machine. Lock entrances

to the shop or disable start

switch or power connection

to prevent unsupervised

use.

Mounting

Mounting Sander

Dust Collection

Once you have confirmed that your machine is

running properly, mount it to a workbench.

DO NOT operate the Model H8192 without

an adequate dust collection system. This

sander creates substantial amounts of wood

dust while operating. Failure to use a dust

collection system can result in short and

long-term respiratory illness.

The strongest mounting option is a "Through

Mount" where holes are drilled all the way through

the workbench, and hex bolts, washers, and

lock nuts are used to secure the sander to the

workbench.

Recommended CFMat EACH Dust Port:

100 CFM

��

Do not confuse this CFM recommendation with

the rating of the dust collector. To determine

the CFM at the dust port, you must consider

these variables: (1) CFM rating of the dust

collector, (2) hose type and length between the

dust collector and the machine, (3) number of

branches or wyes, and (4) amount of other open

lines throughout the system. Explaining how to

calculate these variables is beyond the scope

of this manual. Consult an expert or purchase

a good dust collection "how-to" book.

��

Figure 22. Example of a through mount setup.

To connect a dust collection hose:

Another option for mounting is a "Direct Mount"

where the machine is simply secured to the

workbench with a lag screw.

1. Fit a 2" dust hose from the dust collection

system over each dust port, and secure them

in place with a 2" hose clamp.

2. Tug the hoses to make sure they do not

come off.

��

Note: A tight fit is necessary for proper

performance.

��

Figure 23. Example of a direct mount setup.

Note: To reduce vibration when operating, keep

the rubber cushion included with your sander

between the machine base and the workbench.

5. Slowly, and with light pressure, move the

workpiece into the left side of the sanding

disc. See Figures 24–26 for examples of disc

sanding.

Belt Sanding

Use the sanding belt for the long, flat surfaces of

the workpiece.

To avoid the risk of kickback and personal

injury, always keep the workpiece firmly on

the table, and never sand the short side of

the workpiece with the sanding belt.

To use the sanding belt:

1. DISCONNECT THE SANDER FROM

POWER!

Figure 24. Example of 90° disc sanding.

Belt Tracking

SECTION 6: MAINTENANCE

Lubrication

Always disconnect power

to the machine before

performing maintenance.

Failure to do this may

result in serious personal

injury.

Since all bearings are sealed and permanently

lubricated, simply leave them alone until they

need to be replaced. Do not lubricate them.

Sanding Belt

Tracking

Schedule

For optimum performance from your machine,

follow this maintenance schedule and refer to any

specific instructions given in this section.

The sanding belt must track in the center of the

top pulley to avoid damaging itself during use.

To adjust the sanding belt tracking:

Before Each Use, Check and Correct:

•

Loose mounting bolts.

Damaged or worn sanding belt or disc.

Worn or damaged wires.

1. Turn the sander ON.

2. Observe the sanding belt as it moves over

the top pulley (see Figure 31).

Any other unsafe condition.

After Each Use:

Clean/vacuum dust buildup on tables and

motor.

•

Tracking

Adjustment

Knob

After 50 Hours of Use:

•

Check and correct V-belt tension, damage, or

wear.

Cleaning

Top Pulley

Cleaning the Model H8192 is relatively easy.

Vacuum excess sawdust, and wipe off the

remaining dust with a dry cloth. Wiping the table

clean after every use ensures moisture from wood

dust does not remain on bare metal surfaces.

Figure 31. Sanding belt tracking adjustment.

3. Slowly adjust the tracking adjustment knob

until the sanding belt tracks in the center of

the top pulley.

If any resin has built up, use a resin dissolving

cleaner to remove it. After cleaning, treat all

unpainted cast iron and steel with a non-staining

lubricant with products like G96^®Gun Treatment,

SLIPIT^®, or Boeshield^®T-9.
