QUESTIONS AND ANSWERS SURE A+
✔✔What is the purpose of a GFCI? - ✔✔Senses drop in current and switches power off
✔✔The kind of abrasive material use in grinding wheels for general purpose application
is: - ✔✔aluminum oxide
✔✔Is it safe to carry a portable grinder by the power cord? - ✔✔False
✔✔Is it safe to use standard sockets with electric impact wrenches - ✔✔False
✔✔The larger the power drill, the slower the RPMs and the higher the torque - ✔✔True
✔✔Can you use conventional drill bits with a hammer drill? Why or why not? - ✔✔Yes
of the hammer drill has a switch to turn off hammer action
✔✔Most cordless drills have torque control - ✔✔True
✔✔Prolonged use of power or air tools can cause carpal tunnel sydrome - ✔✔True
✔✔Is it safe to run an impact wrench with a universal joint and socket attached - ✔✔No
because it may throw off attachments
✔✔What conditions would you use a GFCI - ✔✔Wet conditions
✔✔What 3 things does a GFCI protect: - ✔✔1. Overload 2. Overcurrent 3. Ground fault
protection
✔✔A GFCI prevents all electrical shocks - ✔✔False
✔✔Higher voltage on a battery means: - ✔✔Greater power of tool
✔✔What type of power load must be used in the low velocity tool? Why? - ✔✔Power
load with a crimped end must be used cause high power load would get lodged in the
tool
✔✔6 colours ranging from lowest strength to highest strength for power load are: - ✔✔1.
Grey 2. Brown 3. Green 4. Yellow 5. Red 6. Purple
✔✔Power loads should not be carried loosely in pockets or aprons. Why? - ✔✔Could be
set off causing serious injury or death
,✔✔Fasteners used in explosive actuated tools are: - ✔✔Manufactured from special
steel and tempered
✔✔A drive pin is a fastener used to: - ✔✔Permanently attach one material to another
✔✔What is base material? - ✔✔Material which the fastener shank is driven into
✔✔To determine the sustainability of a base material, use a fastener as a centre punch
struck by a single average hammer blow. If the fastener is blunted ( meaning it can't
fasten) the material is too: - ✔✔Hard
✔✔To determine the sustainability of a base material, use a fastener as a centre punch
struck by a single average hammer blow. If the fastener penetrates easily, do not fasten
because the material is too: - ✔✔Soft
✔✔To determine the sustainability of a base material, use a fastener as a centre punch
struck by a single average hammer blow. If the material cracks or shatters, do not
fasten because the material is too: - ✔✔Brittle
✔✔A threaded knurled pin is designed for what material - ✔✔Mild steel
✔✔To be a qualified operator of an explosive actuated tool you must posses: -
✔✔training in the use of each tool and familiarity with local safety regulations
✔✔OH&S states that operators of explosive actuate tools should always wear: - ✔✔Eye
protection
✔✔If a tool is found to be defective, you should: - ✔✔Mark it defective and call a service
representative
✔✔According to OH&S, what safety equipment is required when using an explosive
actuate tool in a confined area such as a small room? - ✔✔ear plugs and eye protection
✔✔Who is responsible if an accident occurs as a result of an unattended explosive
actuated tool? - ✔✔The operator
✔✔Should an explosive actuated tool be used in explosive or flammable area? - ✔✔No
✔✔How often should an explosive actuated tool be cleaned under normal working
conditions? - ✔✔It should be cleaned daily or when it becomes sluggish
✔✔How much oil should be added to the tool parts after cleaning? - ✔✔None
, ✔✔What part requires replacement most often in a low velocity tool? - ✔✔Buffer
✔✔With a low velocity tool, what is a general rule of thumb for the placement and depth
of fasteners in steel? - ✔✔1/2" from the edge, 2" apart and 1/4" deep
✔✔Do not fasten near welds with a low velocity tool because the steel may have been
hardened making the metal brittle - ✔✔True
✔✔Tension load in regards to explosive actuated tools is: - ✔✔a force applied
perpendicular to the base of the material
✔✔Shear load in regards to explosive actuated tools is: - ✔✔a force applied
perpendicular to the fastener
✔✔Bending load in regards to explosive actuated tools is: - ✔✔shear force that is
applied at a distance for the surface base of the material creating a lever-type action on
the fastener
✔✔With a low velocity tool, what is a general rule of thumb for the placement and depth
of fasteners in concrete? - ✔✔3" from the edge and from each other
✔✔How long should you wait if a power actuated tool misfires? - ✔✔30 seconds
✔✔What is another name for a power saw? - ✔✔Reciprocating saw
✔✔What determines the size (capacity) of a power hacksaw? - ✔✔Largest square piece
that can be cut
✔✔Why is the pressure removed from the blade of a power hack saw on the return
stroke? - ✔✔To prevent damage to the blade
✔✔How is the speed of a power hacksaw expressed? - ✔✔Strokes per minute
✔✔Describe the characteristics of a bimetal power hacksaw blade - ✔✔High speed
tooth edge with a tough alloy steel back
✔✔How does the blade set differ from the blade kerf? - ✔✔Kerf is the width the blade
cuts and set is the way individual teeth are bent out of line with the body
✔✔What are the limitations of a horizontal band saw as it relates to cutting curves or
round corners? - ✔✔It can only cut straight
