FOREWORD Put Safety First! This Safety Section contains important information to help you work safely with your machine and describes the dangers inherent in our machines. Some of these dangers are obvious, while others are less evident. It really is important to PUT SAFETY FIRST. Make it a habit to consider the hazards associated with any action BEFORE you do it.

Gloves Experience has shown that careless use of gloves around machinery is a major factor in serious hand injuries. Gloves should not be worn when operating or adjusting the machine, except: Wear protective gloves when handling bandsaw blades at blade changes. Gloves may be worn when handling work pieces, only if the machine is in Manual Mode and the bandsaw blade is not running.

SAFETY HAZARD LABELS The safety hazard labels attached to your machine represent important safety information to help you avoid personal injury or death. All supervisors, operators, and maintenance personnel must locate and understand the safety information associated with each hazard label prior to operating or servicing the machine. The safety hazard labels shown below are located at various positions on the machine to indicate possible safety hazards.

HOLD WORK PIECE FIRMLY AGAINST TABLE • DO NOT REMOVE JAMMED CUTOFF PIECES UNTIL BLADE HAS STOPPED NO MODIFICATIONS TO THE MACHINE ARE PERMITTED WITHOUT PRIOR APPROVAL FROM HYD-MECH. ANY AP- PROVED MODIFICATIONS SHOULD ONLY BE UNDERTAKEN BY TRAINED PERSONNEL.
LIFTING THE S20P WITH A FORK LIFT The S20P is shipped with a shipping pallet attached to the saw. When lifting the pallet with a forklift truck make sure that the load is firmly balanced. Minimum fork length of 72" (1827 mm) is recommended to safely lift the pallet. WRAPPED FOR SHIPPING The S20P is shrink-wrapped for shipping from our plant.
CUTTING FLUID The S20P uses a pump and reservoir to circulate the necessary cutting fluid to the blade for maximum blade life. Your saw blade supplier will be able to provide information to the cutting fluid products that are available for your needs. No cutting fluid (coolant) is supplied with the machine.
SECTION 2 – OPERATING INSTRUCTIONS OPERATOR CONTROL PANEL The operator control panel provides the operator with all the controls necessary to operate the saw after the cutting angle has been set and the stock has been loaded and secured. All of the electrical functions and Feed Rate setting are oper- ated from the control panel.
Manual Mode Machine Operation Manual mode allows for a manual operation of the saw. In this mode all functions are activated be selection of the respec- tive function button on the user interface. To enter the manual mode after the main power has been turned off, press the Machine Start button. Follow the instruc- tions on the display, and select the Manual Mode.
Cycle Parameter Display The machine is capable of displaying many parameters, not all of which can de shown on the screen at the same time. Pressing the CYCLE PARAMETERS button will toggle the display of the parameters. The following is a list of available parameters and the corresponding abbreviations as they are shown on the display.

SETTING the HEAD LINEAR POTENTIOMETER (RHLS/FHLS LIMIT) Cycle through the parameters until the following is on the display: RHLS/FHLS LIMIT HEAD POS = XXX * You must push the RESET button to energize the emergency relays * The head must be lowered until it reaches the mechanical bottom position. In order to execute this operation you must first push the shift button (CYCLE PARAMETERS) and while holding this button depressed then push the (HEAD DOWN) button until the head reaches its bottom limit.
COOLANT FLOW The S20P bandsaw is equipped with a coolant pump supplying coolant flow to four coolant outlets. • The wash gun is provided for clearing chip accumulations. • Guide arm coolant nozzles, one at each guide arm, are equipped with a flow control shut-off valve. The guide arm nozzles should be adjusted to apply an even covering of coolant to the blade.
Variable pitch (following pages), bi-metal blades (like the ¾ or 4/6 bi-metal blade supplied with the Hyd-Mech machine) last much longer, cut faster and more accurately than the conventional carbon steel blades. In order to take advantage of the superiority of bi-metal blades, it is critical to properly “break in” a new blade. This is accomplished by taking two or three cuts through solid four or five-inch diameter mild steel at an extremely slow feed rate.
Page 26
DETERMINE OPTIMUM BLADE PITCH – TEETH PER INCH (T.P.I.) Selecting a blade with proper tooth pitch is important in order to achieve optimal cutting rates and good blade life. For cutting narrow or thin wall structural materials, a fine blade with many teeth per inch (T.P.I.) is recommended. For wide materials a blade with a coarse pitch should be used.
SECTION 3 – MAINTENANCE AND TROUBLESHOOTING SAFETY DURING MAINTENANCE AND TROUBLESHOOTING “Lock-out”, or “Lock-out Tag-out” are terms that refer to procedures taken to prevent the unexpected start-up, or other re- lease of energy, by a machine, whenever anyone is required to remove or bypass safety guards or devices, or whenever anyone is required to place part of his body in a hazard area.
BLADE CHANGING PROCEDURE NOTE: Wear gloves for protection from the sharp blade. . Open the Wheels door by unscrewing the two knobs. 2. Loosen the Blade Tensioner by turning counter clockwise. 3. Open the blade guard at idler guide arm by undoing the mounting screws and removing it as illustrated below.
Page 29
4. Remove the worn blade by sliding it off the wheels and out off both guide blocks 5. Your new blade will be in a coil. While wearing gloves, hold the blade away from yourself; twist the blade to uncoil it.
9. With the blade in place, turn the tensioner handle clockwise until Bade Tension Display shows required value. Recommended blade tension is between 250 - 350 kg. If blade is under tensioned the blade motor will not start. 0. Replace the blade cover and close wheels door. .
Drive Wheel Adjustment The Drive Wheel adjustment is closely linked to adjustment of the Idler Wheel. The purpose of the adjustment is to ensure that the back of the blade remains about .040-.080” away from the wheel flange during rotation. .
CARBIDE REPLACEMENT The blade guide blocks are equipped with one top carbide and two side carbide inserts each. The working life of carbide guides is practically the same as that of the machine itself. However, if required they can be replaced by removing the plate fixing screw as shown.
4. If the blade touches the square at the bottom loosen the top fixing screw “ A’ ” and tighten screws “ B’ ” the same amount until the square edge contacts the blade uniformly along the whole blade width. If contact is at the top of the square, loosen the bottom fixing screw “A”...
As shown, there are two springs on socket head screws holding the brush assembly against the blade. There is also an adjusting stop socket set screw A with a hex nut C on it. This adjusting set screw works as a stop determining the brush position in respect to the blade.
BLADE TENSION SLIDE ADJUSTMENT To reduce the play, which may develop over time between the blade tensioner slide and slide gibs, adjust the screws be- tween the gibs and slide as follows: . Remove the head front cover. 2. Undo blade tension. 3.
LUBRICATION The S20P was designed to minimize the maintenance requirements. Moving assemblies and contact faces need lubrica- tion on a regular schedule whether they are in heavy use or not. The lubrication requirements of the S20P are primarily the saw pivot points which are equipped with grease fittings, and metal to metal surfaces that require lubrication to pre- vent wear and seizure.
SECTION 5 - HYDRAULIC The S20P hydraulic system does not require any special work on a new machine before its start up. The hydraulic tank is filled with FOX YE 32 hydraulic oil and all machine functions have been tested at the factory to ensure proper operation upon initial start up.
SECTION 7 - OPTIONAL EQUIPMENT FOR OPTIONAL ASSEMBLIES SEE PDF ON ATTACHED CD MIST COOLANT SYSTEM Mist Coolant – the air powered pump delivers a regulated number of pulses of lubri- cant to a single applicator nozzle. The unit has two control screws. Pulse / Minute –...
VARIABLE VISE PRESSURE OPTION Vise clamping pressure adjustment is located on the idler side of the machine base. Clamping pressure is indicated by the pressure gauge above the pressure control knob. Turning the knob clockwise increases clamping pressure. The clamp- ing pressure can be changed infinitely form 50PSI to 600PSI (full pump pressure).
