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
