Contact the loose ll insulaon manufacturer for any addion PPE requirements.
HAZARD IDENTIFICATION
Principle of operaon
The insulaon blowing machines that Meyer & Sons manufacturers and sells are machines that have
rotang shas with paddles, pins and vanes designed to break up and move compressed material
(cellulose and berglass) from an open hopper into a pneumac conveying line. Once in that line or
hose, the material is propelled through the hose and exits into an open space (building ac) or an
enclosed space (sidewall). Because of the way in which material is loaded into the machine, the hopper
must be open and therefore moving parts are accessible. The machine likewise has moving drive train
components which must always remain guarded.
Amputaon hazard
The insulaon blowing machine shas are driven by an engine/motor at a relavely high speed. The
shas are connected to the engine or motor via roller chains or transmission belts. The spinning shas
and connected drive train components present a serious personal injury hazard, including but not
limited to amputaon. If any human body part comes in contact with these parts and an immovable
object, such as the machine hopper wall, that body part could be cut o.
Exposure to hazards
In order for the insulaon machine to funcon, material must be able to be placed in an open and
accessible hopper. It is designed such that material can be put into the hopper without personnel
coming into contact with rotang parts. The discharge of the machine is designed to have a hose
aached in order for the insulaon to be blown where it is required. The discharge of the hose must
never be covered by a human hand or other body part and must only be directed to areas where
it cannot come in contact with people and/or human body parts. The drive train components are
guarded and must remain so when the machine is in operaon. There are no adjustments that can be
made to the components while the machine is running.
Training
The owner bears the responsibility to ensure that personnel who may be working on/or operang
the insulaon machine are properly trained. Personnel must be aware that: (1) anything coming into
contact with the moving parts in the machine hopper could be cut o/amputated; (2) if body parts
come in contact with the rotang vanes in the feeder, they will be cut o/amputated; (3) before
working on, cleaning, repairing or maintaining a machine, Lockout/Tagout procedures must be strictly
followed; and (4) the machine must not be operated without guarding in place. Before interacng with
the insulaon machines, personnel must read the Operator’s Manual.

RECEIVING AND INSPECTION
Upon receipt of equipment and material from Meyer, the following basic steps should be taken. The
equipment is heavy and proper handling procedures should be used (See the "Heavy - handle safely"
informaon in the "IMPORTANT SAFETY INFORMATION" secon.)
1. Use the packing list to determine that all the items shipped have been received. Your equipment
was carefully crated for safe shipment when given to the carrier. If Items are missing, contact
Meyer per contact informaon at the end of this secon.
2. Check for damage. Damage in transit is the responsibility of the carrier. Title to your equipment
and all other items in the shipment were transferred to you as soon as the shipment le our dock,
thus it is your responsibility to handle any claim. In the event damage has occurred:
• Be sure to have the driver sign a copy of the freight bill with a notaon about any damage and
contact their oce before the driver leaves your premises.
• Contact the carrier to arrange for an independent inspector to come out to inspect the damage
and prepare the inspecon report. It is imperave that this inspecon is done before you start
to unpack or use any of the equipment.
• If there are any visible problems with your unit or any other items in the shipment, you or the
driver must note in detail the damage on all copies of the freight bill before signing for the
shipment. Then immediately call Meyer.
• Photographic records of the damage are helpful to communicate the extent and type of
damage as well as provide a clear record.

EQUIPMENT SPECIFICATIONS
WIDTH: 63”
DEPTH: 42 1/2”
HEIGHT: 59”
WEIGHT: APPROX. 1,100 LBS.
Machine Installaon
The size of the truck is dictated by the size of the machine, crew, and the number of bags of insulaon
transported. Typically, this is a truck with an 8’ wide X 20’ long box (or longer) and a gross vehicle
weight rang (GVWR) of 21,000 lbs. The recommended minimum is a truck with a 7’ X 14’ box and a
GVWR of 16,000 lbs. In addion, there should be a door on either side of the body and a full width rear
door. This is to provide: proper air ow to allow to aid in the removal of fuel vapors, venlaon for the
air-cooled engine, fresh air for the operator, and help prevent any buildup of dangerous engine exhaust.
Tools and material needed for installaon:
• Drill and drill bits
• 3/8” bolts or lag screws
• Exhaust pipe ngs from the machine to underneath the truck (2 ½” dia.)
• Forkli or other safe means to li the machine
• Pry bar(s)
• Screwdriver, socket and ratchet, saw (hole or saber)

10
1. Move the machine into posion nong that you will need to have access to the rear and le side of
the machine. With the machine in posion; mark the truck oor where the engine exhaust (on the
le side) will go through the oor and mark the base’s mounng hole locaons.
2. The machine can be le in place or moved to provide beer access to the areas that need to be
drilled/cut. Using an 1/8” bit, drill pilot holes to determine if there is anything under the truck oor
that would interfere with the mounng fasteners or the engine exhaust pipe. If there is; move the
holes accordingly.
3. Cut a 3” hole in the oor for the exhaust pipe. Install the ashing (included), center it in the hole
and tack it down.
4. Drill holes for the machine mounng bolts. The size depends on what type and size of fasteners
you are using. Secure the machine to the truck oor.
The engine and exhaust piping could be extremely hot and could cause burns or
ignite a re. Due to the variability of installaons, Meyer cannot provide a guard for
the engine exhaust piping. The installer of the equipment must take the necessary steps to guard this
surface against contact by people or ammable materials.
Engine exhaust piping must be routed away from the side doors to help prevent the
exhaust from entering the truck body or trailer. In addion, it should be routed away
from any ammable materials such as the truck fuel tanks. Ensure that the proper ngs and piping
are used and installed correctly. Failure to do so could lead to serious injury or death.
5. Install the exhaust pipe and ngs (not included). Be sure to securely aach both ends of the
exhaust extension.

SECTION V
MACHINE OPERATING INSTRUCTIONS
Prior to use, the operator must read and understand the enre manual and all the
safety related informaon including all the warnings and guarding instrucons. This
includes but is not limited to reading and understanding the “IMPORTANT SAFETY INFORMATION” and
“HAZARD IDENTIFICATION” Secons. Verify that all guarding is in place and the area is clear of all non-
essenal personnel. Failure to do so could lead to serious injury or death.
Engine exhaust contains carbon monoxide, a poisonous gas that will kill you in
minutes. You CANNOT see it, smell it or taste it. Even if you do not smell exhaust
fumes, you could sll be exposed to carbon monoxide gas. Operate only in well venlated areas. If you
start to feel sick, dizzy, or weak while using this machine, shut it o and get to fresh air immediately.
Seek medical aenon immediately. You may have carbon monoxide poisoning.
The surfaces of the engine and exhaust can be extremely hot. Do not touch or allow
anything to come in contact with the hot parts.
Venlate fuel vapors to reduce the risk of res and explosion. Open all doors on the
truck body/trailer and wait 10 minutes before starng the engine. Leave all doors
open throughout use.
FUEL SAFELY
Fuel is highly ammable. Avoid spills, heat, and buildup of stac electricity. Never fully ll the fuel
tank, allow room for the expansion of the fuel so that when it expands it does not overow. Fill the
tank away from the engine and other sources of heat or open ames. Always ll the tank on the
ground, never in the back of a truck or other vehicle. The tank must be in constant contact with the
ground and the pump nozzle must be in constant contact with the tank during the lling process. This
will lessen the chance of stac electricity buildup. Failure to follow these instrucons could lead to
serious injury or death.
PRE-START CHECKS
1. The operaon of this machine must be limited to people that have read and understood this
manual, the equipment labels, and the proper handling of the insulaon material being installed.
2. Only people involved in the machine operaon are in the vicinity.
3. Check that no foreign material is in the hopper.
4. The doors to the truck body / trailer must be open to provide adequate venlaon for operator and
machine.
5. Check that all guards are in place.
6. The blowing hose is aached to the machine and the person manning the hose is in posion.
7. Check that the switch on the Remote Control Cord is in the OFF posion and connected to the control
panel.
Starng the machine with Remote Control Cord Switch in either the AIR or AIR/
MATERIAL posion will overload the clutch and the engine.
