PPE1.PPE Required:• Lab Coat• Safety Glasses/Goggles
• Additional non-PPE:• Measuring Tape• Pencil• Process Sheet• Cutting List
Surface Planar
Isolate Machine
Inspection of Material
Defects:• Cupping, bowing, warping etc…• Select and mark preliminary face side/ face
edge
Inspect Cutting List
Machine Set up
• Adjust Bridge Guard• Adjust fence to acceptable blade exposure of
10mm• Check that fence is square, adjust if required
Final Check• Note size of rough sawn material.• Ensure bridge guard handle is in appropriate
position (upright) for surfacing face side first.• Unlock Isolator and ensure extraction gate valve is
open and extraction on.
Surfacing Material
Process face side• Ensure blade guard handle in upright position• Ensure correct hand positions and feed• Ensure to measure and re-measure material size
Surfacing Material
Process face edge• Ensure blade guard handle in horizontal position• Ensure correct hand positions and feed• Ensure to measure and re-measure material size
Surfacing Material
Completion of face side/ face edge• Return Machine to safe setting i.e. Isolate• Mark proper face side/face edge
Thicknessing Material
• Ensure correct set up• Measure thickness relative to face side• Adjust settings appropriately to achieve a
thickness of 44mm
Thicknessing Material
Ensure correct set up• Measure thickness relative to face edge• Adjust settings appropriately to achieve a
thickness of 66mm
Thicknessing Material
• Return Machine to Safe Setting• Ensure Machine Stop Mechanism
is engaged
Ripping Material
• Ensure Machine is Isolated• Adjust rip fence for rip cut 1 at 22mm• Adjust rip fence to appropriate position roughly
100mm beyond blade front
Ripping Material
• Ensure blade guard is adjusted to appropriate position• Ensure extractor gate valve is open and extraction is
on• Using rough marking on the end grain indicate the
sections of material to be ripped. • Unlock Isolator• Turn Machine on
Ripping Material• Feed material into saw blade• Ensure correct hand position and movement• Ensure correct use of push sticks to complete rip cut 1• Mark thickness required on rough sawn face of
ripped component
Ripping Material• Adjust rip fence for rip cut 2 at 20mm• Feed material into saw blade• Ensure correct hand position and movement• Ensure correct use of push sticks to complete rip cut 1• Mark thickness required on rough sawn face of ripped
components
Thicknessing Material• Ensure correct set up• Measure material section size• Thickness rip cut 2 components to 38mm• Thickness rip cut 2 components to 18mm• Thickness rip cut 1 component to 20mm
Cross Cutting Material• Isolate Machine• Adjust rip fence to correct position before blade
front to avoid material being trapped during cross cutting
• Cross cut 1 – Set cross cut fence guide to 600mm
Cross Cutting Material600 x 44 x 20 (x1)
• Unlock Isolator• Make trim cut 1 – Ensure correct hand clamping of
material• Drop cross cut fence guide, previously set to 600mm• Reverse material so trim cut end sits flush to cross cut
fence guide• Cross cut material at length of 600mm
Cross Cutting Material300 x 38 x 18 (x2)
• Cross cut 2 – Set rip fence and cross cut fence to 300mm
• Perform trim cut• Cross cut first component to 300mm off rip fence
(ensure correct setting)• Cross cut second component to 300mm off cross cut
fence
Cross Cutting Material150 x 38 x 18 (x2)300 x 38 x 18 (x1)
• Cross cut 3 – Set rip fence to 150mm first (always process shortest lengths first)
• Perform trim cut• Cross cut 150mm (x2)• Reverse material to ensure cut end is in against cross
cut fence guide for final cross cut• Perform final cross cut at 300mm off cross cut fence
Cross Cutting Material
Return Machine to Safe Setting i.e. Isolate Machine
Check
Check cutting list to ensure that the appropriate material has been
processed
