Alcoa Fastening Systems & Rings

I. GENERAL SAFETY RULES:

1. A half hour long hands-on training session with qualified personnel is 

recommended before using Huck equipment.

2. Huck equipment must be maintained in a safe working condition at all 

times. Tools and hoses should be inspected at the beginning of each 

shift/day for damage or wear. Any repair should be done by a qualified 

repairman trained on Huck procedures.

3. For multiple hazards, read and understand the safety instructions be

-

fore installing, operating, repairing, maintaining, changing accessories 

on, or working near the assembly power tool. Failure to do so can result 

in serious bodily injury.

4. Only qualified and trained operators should install, adjust or use the 

assembly power tool.

5. Do not modify this assembly power tool. This can reduce effectiveness 

of safety measures and increase operator risk.

6. Do not discard safety instructions; give them to the operator.

7. Do not use assembly power tool if it has been damaged.

8. Tools shall be inspected periodically to verify all ratings and markings 

required, and listed in the manual, are legibly marked on the tool. The 

employer/operator shall contact the manufacturer to obtain replacement 

marking labels when necessary. Refer to assembly drawing and parts 

list for replacement.

9. Tool is only to be used as stated in this manual. Any other use is pro

-

hibited.

10. Read MSDS Specifications before servicing the tool. MSDS speci

-

fications are available from the product manufacturer or your Huck 

representative.

11.Only genuine Huck parts shall be used for replacements or spares. 

Use of any other parts can result in tooling damage or personal injury.

12.Never remove any safety guards or pintail deflectors.

13.Never install a fastener in free air. Personal injury from fastener eject

-

ing may occur.

14.Where applicable, always clear spent pintail out of nose assembly 

before installing the next fastener.

15.Check clearance between trigger and work piece to ensure there is no 

pinch point when tool is activated. Remote triggers are available for 

hydraulic tooling if pinch point is unavoidable.

16.Do not abuse tool by dropping or using it as a hammer. Never use 

hydraulic or air lines as a handle or to bend or pry the tool. Reason

-

able care of installation tools by operators is an important factor in 

maintaining tool efficiency, eliminating downtime, and preventing an 

accident which may cause severe personal injury.

17.Never place hands between nose assembly and work piece. Keep 

hands clear from front of tool.

18.Tools with ejector rods should never be cycled with out nose assembly 

installed.

19.When two piece lock bolts are being used always make sure the collar 

orientation is correct. See fastener data sheet for correct positioning.

II.  PROJECTILE HAZARDS:

1. Risk of whipping compressed air hose if tool is pneudraulic or pneu

-

matic.

2. Disconnect the assembly power tool from energy source when chang

-

ing inserted tools or accessories.

3. Be aware that failure of the workpiece, accessories, or the inserted tool 

itself can generate high velocity projectiles.

4. Always wear impact resistant eye protection during tool operation. The 

grade of protection required should be assessed for each use.

5. The risk of others should also be assessed at this time.

6. Ensure that the workpiece is securely fixed.

7. Check that the means of protection from ejection of fastener or pintail is 

in place and operative.

8. There is possibility of forcible ejection of pintails or spent mandrels from 

front of tool.

III. OPERATING HAZARDS:

1. Use of tool can expose the operator’s hands to hazards including: 

crushing, impacts, cuts, abrasions and heat.  Wear suitable gloves to 

protect hands.

2. Operators and maintenance personnel shall be physically able to 

handle the bulk, weight and power of the tool.

3. Hold the tool correctly and be ready to counteract normal or sudden 

movements with both hands available.

4. Maintain a balanced body position and secure footing.

5. Release trigger or stop start device in case of interruption of energy 

supply.

6. Use only fluids and lubricants recommended by the manufacturer.

7. Avoid unsuitable postures, as it is likely for these not to allow counter

-

acting of normal or unexpected tool movement.

8. If the assembly power tool is fixed to a suspension device, make sure 

that fixation is secure.

9. Beware of the risk of crushing or pinching if nose equipment is not fit

-

ted.  

IV. REPETITIVE MOTION HAZARDS:

1. When using assembly power tool, the operator can experience discom

-

fort in the hands, arms, shoulders, neck or other parts of the body.

2. When using tool, the operator should adopt a comfortable posture 

while maintaining a secure footing and avoid awkward or off balanced 

postures.

3. The operator should change posture during extended tasks to help 

avoid discomfort and fatigue.

4. If the operator experiences symptoms such as persistent or recurring 

discomfort, pain, throbbing, aching, tingling, numbness, burning sensa

-

tions or stiffness, these warnings should not be ignored. The operator 

should tell the employer and consult a qualified health professional.

V. ACCESSORIES HAZARDS:

1. Disconnect tool from energy supply before changing inserted tool or 

accessory.

2. Use only sizes and types of accessories and consumables that are 

recommended. Do not use other types or sizes of accessories or con

-

sumables.

 

VI. WORKPLACE HAZARDS:

1. Be aware of slippery surfaces caused by use of the tool and of trip 

hazards caused by the air line or hydraulic hose.

2. Proceed with caution while in unfamiliar surroundings; there could be 

hidden hazards such as electricity or other utility lines.

3. The assembly power tool is not intended for use in potentially explosive 

environments.

4. Tool is not insulated against contact with electrical power.

5. Ensure there are no electrical cables, gas pipes, etc., which can cause 

a hazard if damaged by use of the tool.

VII. NOISE HAZARDS:

1. Exposure to high noise levels can cause permanent, disabling hearing 

loss and other problems such as tinnitus, therefore risk assessment 

and the implementation of proper controls is essential.

2. Appropriate controls to reduce the risk may include actions such as 

damping materials to prevent workpiece from ‘ringing’.  

3. Use hearing protection in accordance with employer’s instructions and 

as required by occupational health and safety regulations.

4. Operate and maintain tool as recommended in the instruction hand

-

book to prevent an unnecessary increase in the noise level.

5. Select, maintain and replace the consumable / inserted tool as recom

-

mended to prevent an unnecessary increase in noise.  

6. If the power tool has a silencer, always ensure that it is in place and in 

good working order when the tool is being operated. 

VIII.  VIBRATION HAZARDS:

1. Exposure to vibration can cause disabling damage to the nerves and 

blood supply to the hands and arms.

2. Wear warm clothing when working in cold conditions and keep hands 

warm and dry.

3. If numbness, tingling, pain or whitening of the skin in the fingers or 

hands, stop using the tool, tell your employer and consult a physician.  

4. Support the weight of the tool in a stand, tensioner or balancer in order 

to have a lighter grip on the tool.  

IX. PNEUMATIC / PNEUDRAULIC TOOL SAFETY INSTRUCTIONS:

1. Air under pressure can cause severe injury.

2. Always shut off air supply, drain hose of air pressure and disconnect 

tool from air supply when not in use, before changing accessories or 

when making repairs.

3. Never direct air at yourself or anyone else.

4. Whipping hoses can cause severe injury, always check for damaged or 

loose hoses and fittings.

5. Cold air should be directed away from hands.

6. Whenever universal twist couplings (claw couplings) are used, lock pins 

shall be installed and whipcheck safety cables shall be used to safe

-

guard against possible hose to hose or hose to tool connection failure.
