  • Page 11 BEFORE signing the delivery paperwork. If damage is seen, refuse the shipment and notify Scotchman. DO NOT ACCEPT DAMAGED EQUIPMENT. This makes filing damage claims with the shipping company impossible and will make the customer responsible for the damage repair costs.
  • Page 12 Once the machine is connected, verify that the saw blade rotation is away from the operator when the operator is standing in front of the machine. If the saw blade rotation is wrong, swap two phases of incoming power to the machine. Then check for proper rotation again. ➢...
  • Page 13 4.3 Pressure Regulator The air inlet location is shown below. The air regulator must be set at 6.5 to 7.2 bar (90 to 105 psi). The red knob on top is used to turn the air supply on or off. Do not add oil to the regulator. The pneumatic components of this machine are internally lubricated with grease.
  • Page 14 4.5 Belt Removal and Installation To remove the belt, simply roll it off the pulleys. Do not loosen the motor. Do not pry on the aluminum pulleys or they will get damaged. If the motor has been loosened or removed, it must be realigned. Use a straight edge across the end of the motor pulley and spindle shaft pulley to align the pulleys back again.
  • Page 15 4.7 Priming/Adjusting the Coolant Mister The following procedure explains how to adjust the coolant mister or prime the system if it has run out of coolant. This job requires 2 people in order to safely perform. Make sure to adhere to the following instructions.
  • Page 16 4.8 Cleaning the Coolant Mister The coolant mister can be removed and disassembled for cleaning. It works on a venturi principle. Some of the blade cylinder supply air is diverted to the mister when the blade is advancing up. The air flow through the venturi creates suction that draws the oil from the bottle on the exterior of the machine.
  • Page 17 4.9 Blade Advance Oleo-Pneumatic System The oleo-pneumatic system for the blade advance on a GAA machine is a sealed system. It must be filled with AW32 or 10w non-foaming hydraulic oil. This system can be customer serviced, but it requires advanced hydraulic tools and is therefore usually replaced as a complete assembly pre-filled.
  • Page 18 4.10 Feed Shuttle Oleo-Pneumatic System The oleo-pneumatic converter must be filled with AW32 or 10w nonfoaming hydraulic oil through the threaded plug above the sight glass on the rear of the machine until the level reaches the center of the sight glass.
  • Page 19 5.0 INSTRUCTIONS FOR USE 5.1 Proper and Improper Use This is an automatic cold saw especially designed for cutting non-ferrous material. The use of this machine for cutting ferrous materials is strictly forbidden and may lead to machine damage as well as serious injury.
  • Page 20 5.3 Operation of the Machine MANUAL MODE: One cut at a time. 1. Turn on power at the disconnect switch. The green power lamp (F) should illuminate. 2. Turn the auto/manual switch (O) to the center “hand” position for manual mode. 3.
  • Page 21 5.4 Programming the Parts Counter There have been three different counters installed in the GAA-500-90-NF over its service history. Programming is slightly different for each one. However, the top value is always the number of parts the saw has actually cut and the bottom is the desired setpoint for total number of parts required.
