The purpose of safety symbols is to attract your attention to possible hazardous conditions. This  
manual uses a series of symbols and signal words which are intended to convey the level of  
importance of the safety messages. The progression of symbols is described below. Remember  
that safety messages by themselves do not eliminate danger and are not a substitute for proper  
accident prevention measures.  
Indicates an imminently hazardous situation which, if not avoided,  
WILL result in death or serious injury.  
Indicates a potentially hazardous situation which, if not avoided,  
COULD result in death or serious injury.  
Indicates a potentially hazardous situation which, if not avoided,  
MAY result in minor or moderate injury. It may also be used to alert  
against unsafe practices.  
This symbol is used to alert the user to useful information about

9. USE PROPER EXTENSION CORD. Make  
sure your extension cord is in good condi-  
tion. Conductor size should be in accor-  
dance with the chart below. The amperage  
rating should be listed on the motor or tool  
nameplate. An undersized cord will cause  
a drop in line voltage resulting in loss of  
power and overheating. Your extension  
cord must also contain a ground wire and  
plug pin. Always repair or replace extension  
cords if they become damaged.  
15. USE RECOMMENDED ACCESSORIES.  
Consult the instruction manual for recom-  
mended accessories. The use of improper  
accessories may cause risk of injury.  
16. REDUCE THE RISK OF UNINTENTIONAL  
STARTING. On machines with magnetic  
contact starting switches there is a risk of  
starting if the machine is bumped or jarred.  
Always disconnect from power source  
before adjusting or servicing. Make sure  
switch is turned OFF before reconnecting.

disconnected and after everything has come  
to a complete stop.  
9. BE AWARE THAT CERTAIN WOODS MAY  
CAUSE AN ALLERGIC reaction in people  
and animals, especially when exposed to  
fine dust. Make sure you know what type of  
wood dust you will be exposed to in case  
there is a possibility of an allergic reaction.  
Always wear an ANSI approved respirator!  
4. SUSPENDED DUST PARTICLES IN CON-  
JUNCTION WITH AN IGNITION SOURCE,  
may cause an explosion. Do not operate  
this machine in areas where explosion risks  
would be high if dust were dispersed into  
the area. Areas of high risk include, but are  
not limited to, areas near pilot lights or open  
flames.  
10.THIS MACHINE WILL NOT PROTECT  
AGAINST LEAD-PAINT DUST OR  
ASBESTOS FIBERS. These materials must  
be collected with special equipment because  
of the high hazard to human health. DO NOT  
attempt to collect these materials with this  
machine.  
5. AVOID COLLECTING ANY MATERIAL  
THAT IS BURNING OR SMOKING, this  
includes matches, cigarettes, and hot  
ashes.  
Operations that gener-  
ate large amounts of any  
kind of dust may warrant  
the use of a respirator  
even though the air filter  
is running. The double air  
filter is not a substitute  
for a respirator!  
No list of safety guidelines can be complete.  
Every shop environment is different. Always

is diminished. The following is a list of things to  
keep in mind when determining the placement of  
the air filter:  
Site Planning  
Site planning is an important step to maximize the  
effectiveness of the double air filter. Air circulation  
must be thought out and all obstructions in the air  
path considered.  
Study your shop layout to determine the best  
location for the double air filter. Air flow that is  
obstructed will cause a short cycle effect pro-  
ducing unsatisfactory results. There must be  
a clearance of at least 12" from any obstruc-  
tions in front and back of the unit.  
The G9956 Double Air Filter is supplied with a  
pair of directional vents which allows the user to  
direct the flow of circulation. However, while the  
Place the air filter in front of high dust produc-  
ers like sanders or near areas where sanding  
will take place.  
vents will optimize a good layout, as in  
,
Figure 3  
they will have a limited effect when the double  
air filter is placed incorrectly in the room as in  
Figure 4. When placed too close to obstruc-  
tions, the velocity of the air is lost and circulation  
Do not place the double air filter in the path of  
garage doors or where it may impede trans-  
port or movement of any other object.  
Place the unit in a location that provides easy  
access to turn on, clean and maintain.  
Filter  
Figure 3. Good circulation. The air filter place-  
ment promotes circular air motion.  
Filter  
Figure 4. Poor circulation. Placed too close to  
the wall, the air circulation short cycles leaving  
much of the room unfiltered.

Filter Capacity  
The double air filter must be supported by  
joists when hanging. These joists should be  
capable of supporting at least 150 lbs. DO  
NOT attach the double air filter to sheet rock,  
press board or paneling. These cannot sup-  
port the filter and it may fall.  
The G9956 Heavy-Duty Double Air Filter is  
designed to recirculate the entire volume of air  
in a 20' x 20' x 8' room approximately 26 times  
in one hour. For the best filtering effect, the vol-  
ume in a room should be recirculated at least 6-8  
times every hour.  
To avoid hitting your head on the double air  
filter, make sure there is enough clearance  
between the unit and the ground (at least  
seven feet). This is especially important in a  
basement. If possible, position the air filter in  
an area that has little or no foot traffic but still  
offers easy access to the switch and filters.  
To calculate the recirculating rate for a given  
volume:  
Step 1. Calculate, how long it takes to circulate all  
the volume of air in a room with the double air fil-  
ter; where W = Width, L = Length and H = Height  
of your room, in feet. The rate of air movement for  
the air filter is 1400 cubic feet per minute.  
W' x L' x H'  
Eye Bolts  
= Minutes for circulating 1 time  
1400  
Step 2. Calculate how many times per hour the  
volume is recirculated through the double air filter  
by dividing 60 minutes by the amount of time it  
takes to circulate the volume once. The result is  
listed as times per hour.

from the eyebolts. Remember to account  
for the connecting links and eyebolts on the  
double air filter.  
The double air filter may  
fall and cause serious  
injury if it is not properly  
mounted. DO NOT fasten it  
to sheet rock, press board,  
paneling or anything other  
than joists.  
5. Cut the chain to equal lengths and attach a  
connecting link to each end.  
6. Secure a length of chain to each mounting  
eye.  
Follow these steps and refer to Figure 5 when  
hanging the double air filter.  
7. GET SOME HELP! With at least one other  
person supporting the weight of the double  
air filter, connect the chains to the lag eye  
bolts.  
NOTEDO NOT use hooks in place of lag eye  
bolts. If the double air filter is bumped it could  
fall.

any adjustments, clean-  
ing or maintenance.  
In order to maintain optimal operation, the filters  
in the double air filter should be checked, cleaned  
and/or replaced regularly depending on usage.  
Checking the filters once a week in a small home  
shop is a good habit. Checking them once a day  
during heavy use is important. Always wear a
