UNDERSTOOD, HAVE SOMEONE ELSE READ AND EXPLAIN THE INSTRUCTIONS TO THE OPERATOR OR
CALL THE MANUFACTURER FOR INFORMATION. AN UNINFORMED OPERATOR CAN SUBJECT HIMSELF
AND OTHERS TO SERIOUS INJURY OR DEATH.
WEAR PROPER ATTIRE
Safety glasses are recommended and must be worn if any roof cutting or scraping is being done in the vicinity. Safety glasses
and or face shield are also necessary when working with hot stuff.
Wear properly fitting clothes. Tight clothing can restrict movement and slow down reaction time in a dangerous situation.
Loose fitting clothing can be dangerous and cause serious injury if it gets caught in moving mechanical parts. Wear a longsleeved shirt, buttoned at the cuffs, safety shoes, and pants without cuffs, and knit wrist type gloves.
A hard hat must be worn by operator when working on a job site.
ROOF PREPARATION
INSPECT ROOF DECK
Before allowing equipment and personnel access to roof, make certain roof is strong enough to support the weight. Check
load limits of deck with owner, builder or architect. Clear the work area of all potentially dangerous obstacles that could
cause personal injury to the operator or others. Keep unauthorized people away from construction area. Check to see that all
roof openings are guarded to protect against falls.
WARNING LINE SYSTEM
When operating parallel to roof edge, warning line system must be at least six feet from edge. When operating perpendicular
to edge, warning line must be ten feet from roof edge.

HOISTING TO ROOF
WARNING: ALWAYS CHECK DECK LOAD LIMITS WITH BUILDER, OWNER, OR ARCHITECT
BEFORE DECIDING TO USE ON THE ROOF.
INSPECT THE HOIST
Make certain hoist is in safe operating condition, to be operated by trained personnel. The hoist should be clear of ground
objects and overhead obstacles, such as power lines; it should be secure and properly counterbalanced. Hoist should be
inspected for frayed cables, bent frame members or faulty mechanical parts. Make sure everyone on the ground is completely
clear of the hoisting area. Do not exceed the weight and size capacity of your hoist. Do not use if you are in doubt.
CONNECTING TO LIFT RINGS
There are three lift rings; they are located at the top on the front of the dash and on either side of the chassis at the front of the
machine. Make certain that the cable, chain or sling is setup in a way that you get a balanced load. Hoist roof remover by the
lift rings only or damage or injury could result. Always inspect rings for wear or damage and make sure the hoist, cable,
hook etc. are in good condition or damage or injury may result.

WARNING: ALWAYS DISENGAGE LEVER WHEN ROOF REMOVER IS NOT IN OPERATION.
NEVER LEAVE THE ROOF REMOVER UNATTENDED WITH LEVER ENGAGED.
WARNING: IT IS STRONGLY RECOMMENDED TO DIVERT ALL THE FLOW TO THE
WHEELS BEFORE ENGAGING OR DISENGAGING THE BLADE ACTUATING
LEVER.
WARNING : EXTREME CARE MUST BE TAKEN WHEN OPERATING THIS MACHINE. THE
MACHINE WILL MAKE BRISK AND SUDDEN MOVEMENTS FORWARD AND
REVERSE AND OR TO THE SIDES, IF THE CONTROL ARE USED IN A
CARELESS WAY.
OPERATION
Before Operation
Check to see that engine is serviced properly. Handle gasoline with extreme caution. Never operate machine with
damaged or missing parts. Serious injury may otherwise result. Check machine for leaks, wear on hoses and parts. Repair
and or replace before use.
The Controls (Fig. 3)
The throttle control is located on the engine (refer to the Honda operator’s manual)
Direction is controlled by the two levers at the center of the dash. Left lever controls the left wheel and right lever controls
the right wheel. Pushing forward on these levers will make the machine move forward and pulling back will make the
machine move backward. Moving only one of these handles will make the machine turn. Use caution when turning as the
machine will pivot on the wheels and the front end will swing to the right or left rapidly. Make sure there are no people or
obstacles nearby.
The back and forth motion of the blade is controlled by the lever on the right hand side of the dash. Pulling on this lever will
engage the motion, pushing on it will stop it. Engage this lever swiftly, never leave it midway as the oil will have no way to
go and the relief valve will screech.
The lever on the left side of the dash controls the flow of hydraulic oil to the blade. Moving this lever to the left when the
blade is activated, will increase the number of hits per minute, moving it to the right will decrease the number of hits per
minute, allowing the operator to adjust to the specific roof being removed.
The flow control lever on this machine will divert oil flow from the wheels to the blade. The more flow you use for hitting
with the blade the slower the speed of the wheels. This is ideal because you can operate this machine according to the type of
roof to be removed. If all the flow is directed to the blade, the wheels will have no motion and if all the flow is directed to the
wheels the blade will not actuate.

PROPER OPERATION
After you have prepared for the job in the manner described, and persons who are to use the equipment understand its proper
use and have read through this entire booklet, then the roof remover is ready for operation.
F ERATOR IS FORCED OFF ROOF OR SQUEEZED AGAINST AN OBJECT.
CAUTION: DO NOT TOUCH MUFFLER DURING USE OR JUST AFTER. SEVERE BURNS MAY
RESULT.
Engine Start-up
Check to see that engine is serviced properly. Read Honda owner’s manual. Check oil level and fuel level. Check to see that
spark plug is tight.
After reading through all of the instructions, the 320000 Roof Remover should be ready for operation. When operating
machine for the first time, position the machine on the ground or in an open level area away from obstructions and roof
edges. Start engine and allow warming up for five minutes. Practice manoeuvring the machine by operating the controls as
described earlier.
MAINTENANCE
• See that engine is serviced properly. If service is needed contact an authorized Honda dealer, you will need model
type and serial number of your engine.
GRIZZLY equipment warranty does not cover the engine; it is covered by a separate warranty from Honda.
• Always check tire manufacturer’s recommendations for correct tire pressure before inflating. (Correct tire pressure
should be imprinted on the side of the tire.)
• Check bolts and nuts for tightness every day.
• Check wheel hubs. Tighten or replace if worn.
• Check machine for cracks, wear, warpage, tightness, etc., replace if damaged or in doubt.
• Check oil level at level sight on the left side of the oil tank. Level should be midway in the sight.
• Grease all bearings and blade arms every two hours of operation.
• Grease and adjust chain as needed. Replace if there is excessive play.
• Replace tire when thread is worn, good traction is crucial to the safe operation of the Roof Remover.
• Replace hydraulic oil and filter yearly or sooner if needed, use AW32 hydraulic oil. Dispose of oil and filter at an
approved facility.
• Check hydraulic oil condition, if oil is milky, it is a sign of water in the oil and will need replacing.

SAFETY HAZARDS
Safety hazards are not always obvious to workers. Unlike exposure to health hazards, where illness or injury develop slowly,
safety hazards usually result in immediate injury or death.
Broken bones, cuts, bruises, sprains, burns and loss of limbs, eyesight and hearing are the kinds of injuries caused by safety
hazards.
The rate of occupational injuries in roofing, in fact, ranks in the top ten of all major occupational groups.
Falls
Falls are the number one cause of serious injury and death to roofers. An estimated 10 percent of all roofing accidents result
from falls off roof edges, through roofing openings or off ladders, more than half of the non-fatal accidents result in serious
injury.
Unprotected and unguarded roof edges and roof openings create extremely hazardous conditions.
Ladders with cracked, loose or missing steps: with side rails broken or cracked and not attached firmly to the steps; with
broken, loose or missing locks, or coated with grease, oils or hardened bitumen can lead to serious injury. Ladders should
always be inspected to make sure they’re properly maintained and constructed and that they’re long enough to extend three
feet above the roof’s surface.
Improperly balanced or unstable hoists overturn and will often carry the worker along. Rolls of roofing felt should never be
used as counterweight. Workers should know the load capacity; it should be posted.
9
Burns
Skin contact with hot asphalt and hot coal tar pitch usually results in second and third degree burns. They usually involve
deeper portions of the skin and are easily infected.
An estimated 16 percent of all injuries are burns from hot stuff. The major causes of burns have been from:
Kettle flashes
Kettle splashes from dropping pieces of coal pitch or asphalt into the kettle
Slips and trips while carrying hot bitumen in open containers
Splashes involving transfer operations like from the hot pipe outlet to a hot lugger, from a hot lugger to a mop
cart or a pail, or from the kettle to a pail.
Heavy Lifting
Sprains and strains, a majority of which involve the back, are the most common roofing injury and one of the most severe.
Almost 30 percent of these injuries result in 10 or more days away from work.
Fire/Explosion
Two conditions must be met in order for fires and explosions to occur. First, there must be an ignition source, a welding arc,
spark, cigarette, flame or simply a hot spot as in a kettle or tanker. Secondly, there must be the right mixture of vapours
(from asphalt, pitch, solvents) and oxygen.
For kettles and tankers, fire/explosion conditions arise when:
oversized burners are used to fire the kettle, causing localized overheating of the heating tubes creating a hot spot
the temperature of the bitumen is brought up to the desired operation temperature too quickly allowing the level
of bitumen to drop to the level of the firing tubes, allowing excessively high surface temperatures
heating the bitumen to its flash point (for asphalt, about 525°-540°; for pitch, about 450°-475°)
the temperature of the bitumen is hot enough to reach the auto-ignition level
in tankers, the vent pipe is clogged or plugged so that flammable vapours can build up to explosive levels
©Alcor 2011 All rights reserved
10
Many solvents evaporate quickly at roof temperatures. Explosive mixtures of vapours can be readily formed within confined
spaces like high parapet walls, in atriums or in any space where little or no ventilation exists. And any kind of spark or flame
can ignite the vapours.
Electrocution
Low voltage electricity can cause shock, muscle contractions, breathing difficulty, irregular heartbeat, severe burns and death.
The route that the current takes through the body affects the degree of injury. Current flowing from one finger to another
would not pass vital organ, while from one hand to another would pass through the heart and lungs.
Electrical tools should be properly grounded. The electrical cord should end in a three-prong grounding contact, or the wires
should be enclosed in a metal case with a special grounding attachment.
Employers are required to provide ground fault circuit interrupters for all outlets on construction sites that are not part of the
permanent wiring of the building. This is actually a fast-acting circuit breaker, which can shut off electricity in a fraction of a
second.
Aluminum or other metal ladders pose a serious electrical hazard around electrical equipment and energized lines.
Falling Objects
Tools, bricks, materials, buckets, boxes, pallets or almost anything dropped from a sufficient height can cause severe damage.
Head injuries, one of the highest compensated injuries to workers, often include brain damage.
Workers need protective head gear when working beneath people, tools and equipment.
Flying Objects
Objects can be projected by machines, from welding or grinding operations and can be windblown. Tear-off operations,
where power cutters, power brooms and power spudders are generally used, are the major source of flying substances.
The part of the body most often injured is the eyes.
Unguarded Machinery
Exposed blades and chains on powered machinery like hoists and roof cutters can severely lacerate and crush parts of the
body. Guards should always be fitted over moving parts to protect workers.
