INSTALLATION INSTRUCTIONS1 Optional: Suspend the SPC165 from a balancer.Jarvis part number 4042033 is available.
2 Make the necessary air connection.2.1 The required compressed air supply is 27.3
ft3/min at 90 psi (0.77 m3/min at 6.2 bar).2.2 An air filter/regulator/lubricator (Jarvis part
number 3022003) must be installed in the airsupply line. Keep the lubricator filled at alltimes.
OPERATION INSTRUCTIONS1 Each day, before you begin operation, go throughthe following checklist:1.1 Make sure that the compressed air supply is at
the correct pressure and that the lubricator is upto the full mark. (Use Jarvis Air Mist Lubrica-tor Oil; if using a conventional air mist lubrica-tor set the feed rate at 8--10 drops per minute; ifusing amicro fog air mist lubricator set the feed
rate at 100 drops per minute. Note: Almost allair mist lubricators are of the micro fog type).
1.2 Make sure that the saw moves freely on the ba-lancer, if applicable.
2 Making the cut:2.1 Position the saw.2.2 Depress the trigger fully to start the saw and
make the cut.2.3 When the desired amount of cut is reached, re-
lease the trigger. This will stop the blade fromrotating. Continue holding the saw firmly withboth hands until the blade comes to a completestop.
2.4 Withdraw the saw from the carcass.
