five times, or until there is no dirt or discolorationin the hydraulic fluid. Install a chain andlock on the reservoir filler neck and cap.Hydraulic fluid temperature over 130° is amalfunction. Check the fluid level. Check thefluid for proper viscosity. Check that all machinecycles function through completion, notpartly blocked.b. Gear case oil.NOTE: Drain the blade drive and optionaltable and chip conveyor drive reducer casesafter the first 80 hour run-in period. Flush thecase with a light flushing oil.Filter the old oil, or replace it with fresh oil.Each 2,000 hours of machine operation drainthe reducer cases, flush, and fill with fresh oil.See the contents page for the drive gearreducer bulletin and the drive assembly print.With the machine shut down, proper oil levelis in the centerline of the filler elbow.Add fresh oil as necessary to bring the levelup. W. F. Wells and the gear boxmanufacturer recommend using only MobilSHC 634 synthetic oil. W. F. Wells offers thisoil for sale by the quart. Our part number is900811.It is normal for the gear reducer to operate athousing temperatures up to 200 degrees.Keep finned areas on the case clean to allowmaximum heat dissipation.Keep the breather plug on top of the gearcase filler pipe clear of dirt and greaseaccumulation to avoid contamination enteringthe gear case.2. Variable speed pulleys.Keep the variable speed drive belt andpulley faces free of dirt and grease for longerservice life.Do not use sharp tools, pry bar or screwdriverto separate the pulley faces when changingvariable speed belts. Use a block of wood.Scratches or burrs on a pulley face quicklyruin a new belt.B. Coolant Fluids and Pump.Caution: During machine set up and trial running,unplug the coolant pump at the in-linedisconnect in back of the machine, or fill thecoolant tray. Coolant fluid is a heat sink forthe pump and it must not operate unlesssubmersed in coolant. Routinely clean thecoolant tray and pump screens.A blocked screen stalls the pump.A damaged screen lets chips block or enterthe pump chamber, ruining the pump inminutes. This machine has a 15 galloncoolant reservoir capacity. Consider coolanttype and machine use before filling the reservoirto capacity. Some fluids deteriorate morerapidly than others. The work piece and theblade determine coolant/lubricant type. Thereare coolant fluids and there are cutting fluids.Faster blade speeds require efficient coolantto prevent saw blade overheating. Increasedtool surface speed makes the cutting edgerun hot. Without proper coolant blade metaltemperature passes critical at a given point.Blade teeth soften and dull.1. Straight cutting oil.Slow blade speeds for hard metals and sawblades that remove a large chip require morecoolant/lubricant.At these slow speeds high lubricity straightcutting oil is popular.Do not use straight cutting oil in this machineunless factory labels clearly show machineequipment includes oversize coolant pump,lines and nozzles.2. Water soluble oils.Water soluble oils offer good cooling as wellas good lubrication.Use one part oil to fifteen parts water formost steels.Use one-to-one water and soluble oil for toolsteel sawing.This machine uses this fluid.3. Synthetic oils.Synthetic oils, without chemical solution, aresimilar to water soluble oil capability and dependabilityand used in the same manner.Use one part oil to fifteen parts water foraluminum sawing.A drawback to some synthetic oils is animalfat in the formula which deteriorates in time,and at high temperatures, causingbreakdown of the fats, creating anunpleasant odor. This machine uses thisfluid.4. Chemical solutions.Some cooling/cutting fluid used in high speedaluminum machining and free-machiningalloys contain chemical wetting agents.The application is useful but side effects areharmful to the work piece and the machine.Do not use chemical coolant in this machineunless factory labels clearly show machineequipment includes corrosion resistantpump, hoses, seals and paint.10
C. Mechanical.1. Blade installation.Do not install a blade on this machine beforecompleting the pre-operation check-out.See the Saw Blade Selection and Applicationmanual to select the proper blade for the workpiece.For maximum feed, speed and blade life, requesta reliable blade supplier conduct testsawing on the machine and the work piecewith his recommended blades.WARNING: Blade handling can do greatbodily harm.Wear heavy protective gloves for positivecontrol of the blade.Never wear gloves while operating anymachine tool.Guard against all other body contact withthe blade.Follow blade manufacturer instructions forsafe, proper unpackaging a new blade forinstallation.Do not recoil a used blade. Cut it apart fordisposal. Follow blade manufacturer instructionsfor breaking in a new blade.a. Release blade tension.b. Raise the saw head so the guide armsclear the vise jaws.c. Lock or tag out the electric disconnectswitch.d. Open the blade wheel guard doors.Blade wheels rotate counterclockwise,drawing blade teeth through the work piecefrom left to right against the stationary visejaw.Hold the blade in front of the wheels with teethpointing toward the saw frame. Teeth on thelower blade loop must angle right, toward thestationary vise jaw and drive wheel. If teeth onthe lower loop point toward the frame butangle left, toward the tension wheel, the bandis inside out. Reverse it.(Following applies to grit edge blades as well,doubling blade life when the grit edge dullssawing in one direction, reverse it as follows.)For safety, clear personnel from the area.Loop the band over a guard post or trashbarrel. Twist the band over as far around thecircumference as necessary until the bandsnaps over. As this dulls blade teeth, tellblade suppliers the proper blade weldingconfiguration for the machine.e. Again, hold the blade in front of thewheels with teeth pointing toward the frame,teeth on the lower loop angling right, towardthe stationary vise and drive wheel.f. Place the top of the loop over theframe posts, into the blade guard channel,and onto the wheels.g. Place the bottom of the loop into theblade guards and around the bottom of thewheels. Pull the back of the band up next tothe wheel flanges.h. Tension the blade just enough to takeup slack in the band.i. One guide at a time, take the bladefirmly each side of the guide, twist the teethdown and bring the back edge of the bladeup between the guide rollers.j. Check that the back of the blade isagainst the wheel flanges.Close the blade wheel guard doors.k. Fully tension the blade.l. Raise the saw head.Start the blade and run it 30 seconds.m. Shut down the machine.Check that the back of the blade is close to,but not scrubbing on the wheel flanges. .010to .030 clearance from the back of the bladeto the wheel flange is ideal. Check bladetension before each saw cut.2. Drive belt change.WARNING: Keep fingers outside the pulleyfaces at all times.Do not use sharp tools, pry bar orscrewdriver to separate the pulley faceswhen changing variable speed drive belts.Use a block of wood.Scratches or burrs on a pulley face quicklyruin a new belt.See spare parts to select the proper belt forthe machine.a. Start the machine and turn the bladespeed selector to the lowest speed.b. Lock or tag out the electric disconnect.c. See the index for the drive assemblyprint. Remove the drive guard.11
