What does the overheating of a blade cause?
Black spot
Pink spot
White spot
Green spot
What does ACoP stand for:
Application Code of Practice
Approved Code of Practice
Approved Coaching of Personnel
Approving conduct of Preference
What is recommended in the ACoP in relation to maintenance?
Maintenance is carried out by managers only
An up-to-date maintenance log is kept
Maintenance is only carried out on high risk machinery
Hired equipment should only be maintained by the hire company
A braking device on a planer should stop the block in:
5 seconds
8 seconds
10 seconds
12 seconds
It is noticed that a planer has a serious fault. The best course of action is:
Use it very carefully and then tell a supervisor right away
Isolate the machine, fix the problem yourself and continue to work
Use it carefully and leave the machine so as to not get blamed for the damage.
Isolate the machine, hang a 'Do not use' notice on it and go tell a supervisor
Maintenance should only be carried out by:
Supervisory staff
Anyone who has read the manual
A competent person
A technician
What is the thing to do after fitting a saw blade?
Check the riving knife is correctly fitted and tightened fully
Fill out a risk assessment
Get a supervisor to check the blade
Run it without the guard to check for alignment
Extraction fitted to circular saws reduces:
Noise pollution
Accidents
Off-cuts
Air Pollution
Moving a chisel morticer from side to side when cleaning out a haunch is bad practice because:
It makes the job too quick
It could bend the chisel
The haunch might be wider than required
The haunch might be deeper than required
Stopped work on a planer:
Should never be done
Should only be done by experienced machinists
Can only be done with the proper stops in place
Is easily done
Cutter blocks for use with hand fed planers should not have a cutter projection of more than:
1 mm
1.1 mm
1.2 mm
1.3 mm
A morticer chisel and bit should be set:
Tight to each other
With a 2 mm gap
With the bit protruding the chisel by at least 10 mm
In whatever way looks best, it's unimportant.
Chip thickness limitation tooling:
Reduces the speed of the machine
Limits the maximum depth to which a rebate can be cut
Reduces the severity of a potential injury
Prevents accidents
Before changing knives in a planing machine, it is important to:
Spin the block by hand to ensure the cutter is not catching anything
Remove all the guards
Notify the supervisor
Isolate the machine first
A circular cross cut saw has a 300 mm area marked in yellow on the table each side of the blade. This area is:
A 'No Hands Area'
For storing short off-cuts
Only for the attention of trainees
To indicate the shortest off-cut possible
Which of the following defects causes the timber to bind on the back of a blade during ripping?
Case hardening
Blue stain
Waney edge
Knots
A length of hardwood is being cut along the grain and it is noticed that it is closing on the back of the blade. It is good practice to:
Pull the timber back towards the operative to try to cut again
Push the uncut end of the timber down in order to lift it away from the blade
Drive a wedge in the end of the cut to ease the friction
Ignore it and keep pushing harder using a push stick
When running test pieces it is always important to:
Keep one of the guards unset to enable a clear view
Unset all guards and be careful
Push the work through very slowly
Have all the guards in place
Large heavy sections of timber should be:
Carried by strong people
Lifted mechanically if at all possible
Moved by as many people as possible
Always cut in half
If a smaller blade than normal is fitted to a circular saw:
The peripheral speed will decrease
The peripheral speed will increase
The nut will have to be done up very tightly
The blade will have to be very sharp
After completing work on a narrow band saw it is important to:
Tighten the tension to ensure the blade condition is retained
Release the tension so the blade does not suffer damage
Sharpen the saw blade with an appropriate file
Always remove the blade, fold it and store it in the machine shop
