Some dust created by power sanding, sawing, grinding, drilling, and
other construction activities contains chemicals known to the State
of California to cause cancer, birth defects or other reproductive
harm. Some examples of these chemicals are:
• Lead from lead-based paints.
• Crystalline silica from bricks, cement and other masonry products.
• Arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you
do this type of work. To reduce your exposure to these chemicals:
Work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter
out microscopic particles.

Glossary Of Terms
The maximum volume
of air (rated in CFM) that a dust collector can
move, at the inlet, when fully assembled and
not connected to any ducting.
A secondary length of duct that
connects a dust-producing machine to the
Main Line of a permanent dust collection system. The minimum recommended Velocity for
branch lines is 4000 FPM.
The part of the dust col-
lector that holds the majority of captured dust.
A measurement
describing the volume of air that moves through
an area in one minute. CFM = Velocity (FPM) x
Cross-Sectional Area of Duct (ft.
A type of two-stage dust collector that
uses centrifugal force to remove large dust particles before they can reach the filter.
Metal/plastic pipe or hose that
connects the dust collector to dust-producing
machines. Typically available in rigid or flexible
options.
The entire assembly of
dust collector, duct, and fittings used to capture
dust from machines.
The part of a dust-producing
machine that connects to dust collection duct.

).
Duct Grounding: A method of using bare wire
with plastic duct to safely dissipate static elec
tricity buildup during operation.
Main Line: The primary length of duct that con
nects the dust collector to the branch lines of
a permanent dust collection system. The mini
mum recommended Velocity for main lines is
3500 FPM.
Machine CFM Requirement: Indicates the mini
performance required by the
System after accounting for the drop in CFM
from the static pressure loss of the duct line
between the machine and the dust collector.
Powered Air Filter: An independently operated
machine that removes fine dust suspended in
producing operations as a secondary method
to improve the air quality in a shop.
Single-Stage Collector: A type of dust collector
directly into the filter.
Static Pressure: Expressed in units of inches of
between the air inside and outside the dust col
the blower.
The part of the dust collector that prevents
the majority of suctioned dust from returning to
the shop environment. Filters are rated by the
size of fine dust (measured in microns) that can
pass through them.
duct connections that allow the branch and
main lines of a dust collection system to be
routed from the machine to the dust collector.

SECTION 1: SAFETY
For Your Own Safety, Read Instruction
Manual Before Operating This Machine
The purpose of safety symbols is to attract your attention to possible hazardous conditions.
This manual uses a series of symbols and signal words 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. Always use common sense and good judgment.
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.
Alerts the user to useful information about proper operation of the
NOTICE
machine to avoid machine damage.
Safety Instructions for Machinery
OWNER’S MANUAL. Read and understand this
owner’s manual BEFORE using machine.
TRAINED OPERATORS ONLY. Untrained operators have a higher risk of being hurt or killed.
Only allow trained/supervised people to use this
machine. When machine is not being used, disconnect power, remove switch keys, or lock-out
machine to prevent unauthorized use—especially
around children. Make your workshop kid proof!
DANGEROUS ENVIRONMENTS. Do not use
machinery in areas that are wet, cluttered, or have
poor lighting. Operating machinery in these areas
greatly increases the risk of accidents and injury.
MENTAL ALERTNESS REQUIRED. Full mental
alertness is required for safe operation of machinery. Never operate under the influence of drugs or
alcohol, when tired, or when distracted.
ELECTRICAL EQUIPMENT INJURY RISKS.
You can be shocked, burned, or killed by touching
live electrical components or improperly grounded
machinery. To reduce this risk, only allow qualified
service personnel to do electrical installation or
repair work, and always disconnect power before
accessing or exposing electrical equipment.
DISCONNECT POWER FIRST.
nect machine from power supply BEFORE making adjustments, changing tooling, or servicing
machine. This prevents an injury risk from unintended startup or contact with live electrical components.
EYE PROTECTION. Always wear ANSI-approved
safety glasses or a face shield when operating or
observing machinery to reduce the risk of eye
injury or blindness from flying particles. Everyday
eyeglasses are NOT approved safety glasses.
Always discon-

Page 14
WEARING PROPER APPAREL. Do not wear
clothing, apparel or jewelry that can become
entangled in moving parts. Always tie back or
cover long hair. Wear non-slip footwear to reduce
risk of slipping and losing control or accidentally
contacting cutting tool or moving parts.
HAZARDOUS DUST. Dust created by machinery
operations may cause cancer, birth defects, or
long-term respiratory damage. Be aware of dust
hazards associated with each workpiece material. Always wear a NIOSH-approved respirator to
reduce your risk.
HEARING PROTECTION. Always wear hearing protection when operating or observing loud
machinery. Extended exposure to this noise
without hearing protection can cause permanent
hearing loss.
REMOVE ADJUSTING TOOLS. Tools left on
machinery can become dangerous projectiles
upon startup. Never leave chuck keys, wrenches,
or any other tools on machine. Always verify
removal before starting!
USE CORRECT TOOL FOR THE JOB. Only use
this tool for its intended purpose—do not force
it or an attachment to do a job for which it was
not designed. Never make unapproved modifications—modifying tool or using it differently than
intended may result in malfunction or mechanical
failure that can lead to personal injury or death!
AWKWARD POSITIONS. Keep proper footing
and balance at all times when operating machine.
Do not overreach! Avoid awkward hand positions
that make workpiece control difficult or increase
the risk of accidental injury.
CHILDREN & BYSTANDERS. Keep children and
bystanders at a safe distance from the work area.
Stop using machine if they become a distraction.
GUARDS & COVERS. Guards and covers reduce
accidental contact with moving parts or flying
debris. Make sure they are properly installed,
undamaged, and working correctly BEFORE
operating machine.
FORCING MACHINERY. Do not force machine.
It will do the job safer and better at the rate for
which it was designed.
NEVER STAND ON MACHINE. Serious injury
may occur if machine is tipped or if the cutting
tool is unintentionally contacted.
STABLE MACHINE. Unexpected movement during operation greatly increases risk of injury or
loss of control. Before starting, verify machine is
stable and mobile base (if used) is locked.
USE RECOMMENDED ACCESSORIES. Consult
this owner’s manual or the manufacturer for recommended accessories. Using improper accessories will increase the risk of serious injury.
UNATTENDED OPERATION. To reduce the
risk of accidental injury, turn machine OFF and
ensure all moving parts completely stop before
walking away. Never leave machine running
while unattended.
MAINTAIN WITH CARE. Follow all maintenance
instructions and lubrication schedules to keep
machine in good working condition. A machine
that is improperly maintained could malfunction,
leading to serious personal injury or death.

Additional Safety for Dust Collectors
To reduce risk of start-
of death or injury caused by explosions or fires, DO
Long-term respiratory damage can occur from using dust collectors without proper use of a
respirator. Fire or explosions can result in smoke inhalation, serious burns, or death—if machine
is used to collect incorrect materials, is operated near potential explosion sources, or ducting is
improperly grounded. Entanglement, amputation, or death can occur if hair, clothing, or fingers
are pulled into the inlet. To reduce the risk of these hazards, operator and bystanders MUST
completely heed the hazards and warnings below.
INTENDED USE. Collecting the wrong materi-
als can result in serious inhalation hazards, fire,
explosions, or machine damage. This machine
is ONLY designed to collect wood dust and chips
from woodworking machines. DO NOT use it to
collect silica, polyurethane, toxic fumes, metal dust
or shavings, lead paint, drywall, asbestos, biohazards, explosive dusts, flammable or combustible
liquids or fumes, nor burning or smoking material.
WEAR A RESPIRATOR. Fine dust that is too
small to be caught in filter will be blown into ambient air. Always wear a NIOSH-approved respirator during operation and for a short time after to
reduce your risk of permanent respiratory damage.
Never collect dust from any hazardous material.
IMPELLER HAZARDS. To reduce risk of entanglement or contact with impeller, DO NOT place
hands, hair, clothing, or tools in or near open dust
collection inlet during operation, and keep small
animals and children away. The powerful suction
could easily pull them into impeller.
HAZARDOUS DUST. Dust exposure created while
using machinery may cause cancer, birth defects,
or long-term respiratory damage. Be aware of dust
hazards associated with each workpiece material,
and always wear a NIOSH-approved respirator.
EMPTYING DUST. When emptying bag or drum,
wear respirator and safety glasses. Empty dust
away from ignition sources and into approved
container.
OPERATING LOCATIO N. To reduce respiratory
exposure to fine dust, locate permanently installed
dust collectors away from working area or in another room. DO NOT place dust collector where it can
be exposed to rain or moisture, which creates a
shock hazard and will reduce life of machine.
POWER DISCONNECT. Turn machine OFF, dis-
connect from power supply, and allow impeller
to completely stop before leaving machine unattended, or doing any maintenance or service.
REGULAR CLEANING.
ing a fire, regularly check/empty collection bags
or drum to avoid buildup of fine dust, which can
increase risk of fire. Regularly clean surrounding
area where machine is operated—excessive dust
buildup on overhead lights, heaters, electrical panels, or other heat sources will increase risk of fire.
SUSPENDED DUST PARTICLES. To reduce risk
NOT operate in areas where these risks are high,
including spaces near pilot lights, open flames, or
other ignition sources.
AVOIDING SPARKS. To reduce risk of fire, avoid
collecting any metal objects or stones. These can
possibly produce sparks when they strike impeller,
which can smolder in wood dust for a long time
before a fire is detected. If you accidentally cut
into wood containing metal, immediately turn OFF
dust collector, disconnect from power, and wait
for impeller to stop. Then empty bag or drum into
approved airtight metal container.
FIRE SUPPRESSION. Only operate dust collector
in locations that contain fire suppression system or
have fire extinguisher nearby.
STATIC ELECTRICITY. To reduce risk of fire or
explosions caused by sparks from static electricity,
ground all ducting using grounding wire.
DUST ALLERGIES. Dust from certain woods will
cause an allergic reaction. Make sure you know
what type of wood dust you will be exposed to in
case of an allergic reaction.

SECTION 2: POWER SUPPLY
Before installing the machine, consider the availability and proximity of the required power supply
circuit. If an existing circuit does not meet the
requirements for this machine, a new circuit must
be installed. To minimize the risk of electrocution,
fire, or equipment damage, installation work and
electrical wiring must be done by an electrician or
qualified service personnel in accordance with all
applicable codes and standards.
or equipment damage
may occur if machine is
not properly grounded
and connected to power
The full-load current rating is the amperage a
machine draws at 100% of the rated output power.
On machines with multiple motors, this is the
amperage drawn by the largest motor or sum of all
motors and electrical devices that might operate
at one time during normal operations.
The full-load current is not the maximum amount
of amps that the machine will draw. If the machine
is overloaded, it will draw additional amps beyond
the full-load rating.
If the machine is overloaded for a sufficient length
of time, damage, overheating, or fire may result—
especially if connected to an undersized circuit.
To reduce the risk of these hazards, avoid overloading the machine during operation and make
sure it is connected to a power supply circuit that
meets the specified circuit requirements.
For your own safety and protection of
A power supply circuit includes all electrical
equipment between the breaker box or fuse panel
in the building and the machine. The power supply circuit used for this machine must be sized to
safely handle the full-load current drawn from the
machine for an extended period of time. (If this
machine is connected to a circuit protected by
fuses, use a time delay fuse marked D.)
Note: Circuit requirements in this manual apply to
a dedicated circuit—where only one machine will
be running on the circuit at a time. If machine will
be connected to a shared circuit where multiple
machines may be running at the same time, consult an electrician or qualified service personnel to
ensure circuit is properly sized for safe operation.
This machine is prewired to operate on a power
supply circuit that has a verified ground and meets
the following requirements:
This machine can be converted to operate on a
power supply circuit that has a verified ground
and meets the requirements listed below. (Refer
to Voltage Conversion instructions for details.)

Grounding Requirements
This machine MUST be grounded. In the event
of certain malfunctions or breakdowns, grounding
reduces the risk of electric shock by providing a
path of least resistance for electric current.
Improper connection of the equipment-grounding
wire can result in a risk of electric shock. The
wire with green insulation (with or without yellow
stripes) is the equipment-grounding wire. If repair
or replacement of the power cord or plug is necessary, do not connect the equipment-grounding
wire to a live (current carrying) terminal.
Check with a qualified electrician or service personnel if you do not understand these grounding
requirements, or if you are in doubt about whether
the tool is properly grounded. If you ever notice
that a cord or plug is damaged or worn, disconnect it from power, and immediately replace it with
a new one.
We do not recommend using an extension cord
with this machine.
cord, only use it if absolutely necessary and only
on a temporary basis.
Extension cords cause voltage drop, which can
damage electrical components and shorten motor
life. Voltage drop increases as the extension cord
size gets longer and the gauge size gets smaller
(higher gauge numbers indicate smaller sizes).
Any extension cord used with this machine must
be in good condition and contain a ground wire
and matching plug/receptacle. Additionally, it must
meet the following size requirements:
For 110V operation: This machine is equipped
with a power cord that has an equipment-grounding wire and a grounding plug (see following figure). The plug must only be inserted into a matching receptacle (outlet) that is properly installed
and grounded in accordance with all local codes
and ordinances.
For 220V operation: The plug specified under
“
page has a grounding prong that must be attached
to the equipment-grounding wire on the included
power cord. The plug must only be inserted into
a matching receptacle (see following figure) that
is properly installed and grounded in accordance
with all local codes and ordinances.

SECTION 4: DESIGNING THE
You have many choices regarding main line and
branch line duct material. For best results, use
smooth metal duct for the main line and branch
lines, then use short lengths of flexible hose to
connect each machine to the branch lines.
Plastic duct is also a popular material for home
shops. However, be aware that there is a fire or
explosion hazard if plastic duct material is not
properly grounded to prevent static electrical
buildup (refer to

this section)

The popularity of plastic duct is due to the fact
that it is an economical and readily available
product. It is also simple to assemble and easily
sealed against air loss. The primary disadvantage
of plastic duct for dust collection is the inherent
danger of static electrical buildup.

The Model G0777/G0777HEP is designed to collect dust from one machine at a time. This can
be accomplished by either connecting it to one
machine at a time or by connecting it to multiple
machines and using blast gates to control which
branch is active.
The Model G0777/G0777HEP works quite well as
a point-of-use dust collector. The wheels make it
easy to move around the shop near the machine
being used.

• Keep ducts between the dust collector and
machines as short as possible.
• Keep ducting directional changes to a mini-
mum. The more curved fittings you use, the
greater the loss of suction at the dust producing machine.
• Gradual directional changes are more effi-
cient than sudden directional changes (i.e.
use 45° elbows in place of 90° elbows whenever possible).
• The simpler the system, the more efficient
and less costly it will be.

There are also many kinds of pure plastic flexible
hose, such as non-perforated drainage type hose
and dryer vent hose. Drainage type hose, while
being economical, does not quite have the flexibility required for dust collection. The inside of the
duct is also deeply corrugated and can increase
the static pressure loss by as much as 50% over
smooth wall duct. Dryer vent hose, while being
completely flexible, is non-resistant to abrasion
and has a tendency to collapse in a negative
pressure system. We DO NOT recommend using
dryer vent hose in your dust collection system.
If using flex-hose, you should choose one of the
many types that are designed specifically for the
movement of solid particles, i.e. dust, grains,
and plastics. However, the cost of specifically
designed flexible duct can vary greatly. Grizzly
offers polyethylene hose, which is well suited for
the removal of particulate matter, especially sawdust, since it is durable and completely flexible.
Polyethylene is also very economical and available in a wide variety of diameters and lengths for
most applications.
Flexible hose is generally used for short runs,
small shops and at rigid duct-to-tool connections.
There are many different types of flex hose on
the market today. These are manufactured from
materials such as polyethylene, PVC, cloth hose
dipped in rubber and even metal, including steel
and aluminum.
The superior choice here is metal flex hose that is
designed to be flexible, yet be as smooth as possible inside to reduce static pressure loss.
There are a number of options when it comes to
metal duct, but metal duct that is specially manufactured for dust collection is the best choice.
When selecting your metal duct, choose high
quality metal duct with smooth welded internal
seams that will minimize airflow resistance. This
type of duct usually connects to other ducts or
elbows with a simple, self-sealing clamp, is very
quick and easy to assemble, and can be readily dismantled and re-installed in a different configuration. This is especially important if you ever
need to change things around in your shop or add
more tools.
Avoid inferior metal duct that requires you to cut it
to length and snap it together. This type of duct is
time consuming to install because it requires you
to seal all the seams with silicone and screw the
components on the ends with sheet metal screws.
Another disadvantage is the rough internal seams
and crimped ends that unavoidably increase static
Metal Duct
Advantages of metal duct is its conductivity and
that it does not contribute to static electrical
charge build-up. However, static charges are still
produced when dust particles strike other dust
particles as they move through the duct. Since
metal duct is a conductor, it can be grounded quite
easily to dissipate any static electrical charges.

components (see Accessories on Page 40).

System Design
For most small-to-medium sized shops, you can
design and build the dust collection system yourself without hiring engineers or consultants. We
have included some basic information here to get
you started on a basic design.
If you have a large shop or plan to design a complicated system, we recommend doing additional
research beyond this manual or seeking the help
of an expert.
When designing a successful dust collection system, planning is the most important step. In this
step, sketch a basic layout of your shop, including
space requirements of different machines.

Don't worry, non-Grizzly brand machines can be
substituted with Grizzly machines for layout purposes.
After you're finished, make sure to
save your layout for later modification.
Your sketch only needs the basic details of the
shop layout, similar to
ing all your current/planned machines and your
planned placement of the dust collector
For the next step, sketch how you will connect
your machines to the dust collector. Consider
these general guidelines for an efficient system:

Since each machine produces a different amount
of sawdust, the requirements for the minimum
amount of CFM to move that sawdust is unique
to the machine (for example, a planer produces
more sawdust than a table saw). Knowing this
required CFM is important to gauging which size
of duct to use.
Refer to the

the airflow each machine requires. Keep in mind
that machines that generate the most sawdust
should be placed closest to the dust collector.

Determining Main Line Duct Size
The general rule of thumb for a main line duct is
that the velocity of the airflow must not fall below
3500 FPM.
For small/medium sized shops, using the inlet size
of the dust collector as the main line duct size
will usually keep the air velocity above 3500 FPM
and, depending on your system, will allow you to
keep multiple branches open at one time.
Mark your drawing, as shown in the
below,
but using the inlet size for your dust collector as
the main line.
The general rule of thumb for a branch line duct is
that the velocity of the airflow must not fall below
4000 FPM.
For small/medium sized shops, using the dust
port size from the machine as the branch line duct
size will achieve the correct velocity in most applications. However, if the dust port on the machine
is smaller than 4", make the branch line 4" and
neck the line down right before the dust port.
Note: Systems with powerful dust collectors work
better if multiple blast gates are left open. This
also allows you to run two machines at once.
Experiment with different combinations of blast
gates open/closed to find the best results for your
system.
Write your determined branch line sizes on your
drawing, as shown in the following figure.
If two machines will connect to the same branch
line and both will operate at the same time, then
add the required CFM for each machine together

In most small/medium shops it is only necessary
to calculate the line with the longest duct length or
the most fittings (operating under the assumption
that if the line with the highest resistance works,
the others will be fine).
To calculate the static pressure of any given
line in the system, follow these steps:
1.
the
2.
pressure loss given in the previous table.
Adding duct work, elbows, branches and any
other components to a duct line increases airflow
resistance (static pressure loss). This resistance
can be minimized by using rigid (smooth) duct
and gradual curves, as opposed to flexible duct
and 90˚ elbows.
To help you think about this resistance, imagine
riding a bicycle in a tunnel that is an exact replica
of your duct work. If the inside of the tunnel is very
bumpy (flexible
) and has a lot of sharp turns
(90˚ elbows), it will take a lot more effort to travel
from one end to the other.
The purpose of calculating the resistance is to
determine if it is low enough from the machine to
the dust collector to meet the given CFM requirement for the machine. Use the
to
calculate the resistance of duct work.

System Grounding
Since plastic hose is abundant, relatively inexpensive, easily assembled and air tight, it is a very
popular material for conveying dust from woodworking machines to the dust collector.
We recommend only using short lengths of flexible hose (flex-hose) to connect the woodworking
machine to the dust collector. However, plastic
flex-hose and plastic duct are an insulator, and
dust particles moving against the walls of the
plastic duct create a static electrical buildup. This
charge will build until it discharges to a ground.
If a grounding medium is not available to prevent
static electrical buildup, the electrical charge will
arc to the nearest grounded source. This electrical discharge may cause an explosion and subsequent fire inside the system.
To protect against static electrical buildup inside
a non-conducting duct, a bare copper wire should
be placed inside the duct along its length and
grounded to the dust collector. You must also
confirm that the dust collector is continuously
grounded through the electrical circuit to the electric service panel.
If you connect the dust collector to more than one
machine by way of a non-conducting branching
duct system and blast gates, the system must still
be grounded as mentioned above. We recommend inserting a continuous bare copper ground
Always guard against
by grounding all dust
We also recommend wrapping the outside of all
plastic ducts with bare copper wire to ground
the outside of the system against static electrical
buildup. Wire connections at Y’s and T’s should
be made with wire nuts.
Attach the bare ground wire to each stationary
woodworking machine and attach to the dust
collector frame with a ground screw as shown
in the
continuously grounded to the grounding terminal
in your electric service panel.
Be sure that you extend the bare copper wire down
all branches of the system. Do not forget to connect the wires to each other with wire nuts when
two branches meet at a “Y” or “T” connection.
Ensure that the entire system is grounded. If using
plastic blast gates to direct air flow, the grounding wire must be jumped (see the figure below)
around the blast gate without interruption to the
grounding system.

The remaining dust travels past the impeller and
is then caught by the filter cartridge and deposited
in the plastic collection bag below. This spunbond polyester filter catches 99% of particles from
0.2 to 2 microns in size, and is pleated to provide
maximum surface area for efficient airflow.
G0777HEP Only: The MERV-17 HEPA filter
catches an additional 99.97% of particles at 0.3
microns.
To maintain CFM during heavy dust collection
operations, the cleaning hand crank is manually rotated and the internal filter flaps knock off
caked-on dust into the plastic collection bag.

Using Controls
A remote control receiver and remote controller
(see Figure 60) allow the dust collector to be
turned ON and OFF from up to 75 feet away, providing that direct line-of-sight is maintained.
To prevent accidental startups by other common
RF items like garage door openers, the remote
control signal for the Model G0777/G0777HEP is
IR (infrared) rather than a RF (radio frequency)
signal. The remote control switch features a factory-set 256-code channel setting, which prevents
the simultaneous startup of two G0777's.
The Model G0777/G0777HEP is equipped with a
circuit breaker/thermal overload button. If the dust
collector experiences an overload, this button
pops out and the machine shuts down.
To restart the machine, you must first fix the cause
of the overload, press the circuit breaker/thermal
overload button, then turn the power switch OFF,
then ON to reset the thermal overload.

crank handle-driven filter flap system (see Figure
73) for removing any built-up dust and debris from
the filter pleats.
Schedule
For optimum performance from your machine,
follow this maintenance schedule and refer to any
specific instructions given in this section.
Daily Check:
• Dust collector is completely powered down at
the end of use.
• Dust collection drum or bag leaks.
• Loose mounting bolts.
• Suction leaks.
• Worn or damaged wires.
• Any other condition that would hamper the
safe and efficient operation of this machine.
Emptying Drum
Empty the collection drum when it is approximately
3
⁄4 full. If the drum becomes overfilled, the dust
will be sucked into the intake barrel and passed
through to the canister filter.
How quickly the drum will fill up is based on the
type of work being done at the time:
• Fine dust from a sander or table saw will
slowly fill the drums.
Crank

Figure 73. Crank handle-driven filter flap system
for cleaning canister filters (G0777 shown).
To clean the filter, rotate the crank handle a few
turns in one direction. The caked-on dust and
debris will fall into the plastic bag below.
For a more thorough cleaning every few months
under heavy use, remove the filter from the dust
collector (see Page 46) and rinse it with warm
water. Allow the filters to air dry only. Do not leave
the filters in the sun to dry or apply heat to speed
the process; heat exposure can damage your
filters.
• Curly shavings from a planer or jointer will
quickly fill the drums.
When first using the dust collector, check the
drum regularly to get an idea of how often it needs
to be emptied.
