=Safety Precautions/Loss Prevention=
#Operator must be wearing safety glasses.
#Saw location requires operators to be wearing steel-toed boots and green coat.
#Do not operate saw without prior training.
=Standard Operation Procedure=
==Sample and Machine Set-Up==
#Briefly check machine for unsafe conditions: broken or loose blade, sharp or flammable metal scraps, E-STOP button.
#Secure sample in vice while saw is off.
#* The vice on this saw is a bit old and crooked. This makes securing smaller samples difficult. Use other pieces of metal or available guide to even out the vice while you are securing your sample.
#Make initial adjustments to both saw pressure and cutting fluid.
#*An operator can change the pressure of the blade during sawing with the dial shown in Figure 2 at the bottom of the page. If you know you are sawing a soft material, start at a pressure below “3”. If you are sawing a harder metal, start with the saw pressure at “3” and work up in pressure as needed.
#*The cutting fluid flow lever’s location can be seen in Figure 1. If you are sawing a soft material, please ensure that this is in the on position. This will help keep the blade from becoming gummed-up during use. Add more cutting fluid to saw by pouring water/lubricant mixture through one of the saw’s drains. Fluid should appear milky if it has an adequate amount of lubricant for sawing.
==Machine Operation==
#Turn on saw by turning the “ON/OFF” switch (Figure 1).
#The blade will begin moving once the “START” button is pressed. Guide the blade down until it meets your sample.
#*If your sample begins to shift in the vice at any point of sawing, press the “STOP” button immediately! A moving sample can cause the blade to snap!
#Move the cutting fluid nozzle so that the blade is lubricated.
#Adjust the saw pressure until you find the proper setting for your material. Pressure is optimal when each pass of the saw blade creates small shavings and not a curled, attached bit of material.
#The saw will stop automatically once it reaches the bottom of the sample. Stop the saw at anytime by pressing “STOP” as well.
#Raise the blade by holding down the “STOP” button.
#Turn off saw’s “ON/OFF” switch and remove sample.
#Vaccum/sweep up all shavings and appropriately dispose of them.
