Page 15: Section 1 - Installation
SAFETY PRECAUTIONS The S20P has been designed to give years of reliable service. It is essential that operators be alerted to the safe opera- tion of this saw, and the practices to avoid that could lead to injury. The following safety rules are at the minimum neces- sary for the safe installation, operation, and maintenance of the saw. -
Page 16: Lifting The S20P With A Fork Lift
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. -
Page 17: Cutting Fluid
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. -
Page 18: Section 2 - Operating Instructions
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 operat- ed from the control panel. -
Page 19: Manual Mode Machine Operation
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. -
Page 20: Cycle Parameter Display
Cycle Parameter Display The machine is capable of displaying many parameters, not all of which can be 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. -

Page 22: Setting The Head Linear Potentiometer (Rhls/Fhls Limit)
HEAD SWING and BREAK An integral function of the S20P is the ability to make mitered cuts at angles between 90 and 30 degrees. The Head swing of the S20P is easily changed to set a different cutting angle by first releasing the Angle Brake lever, and then manually moving the Head to the cutting angle desired. -
Page 23: Coolant Flow
GUIDE ARM POSITIONING The S20P idler side guide arm is adjustable to accommodate varying material widths. The guide arm should be adjusted as close to the material as possible while still allowing it to pass. This process of matching the guide arm spacing to the material size is important to optimize blade life and ensure straightness of the cut. -
Page 24: Blade Basics
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 25 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.

Page 26: Section 3 - Maintenance And Troubleshooting
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. -
Page 27: Blade Changing Procedure
BLADE CHANGING PROCEDURE NOTE: Wear gloves for protection from the sharp blade. 1. 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 28 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 1250 - 1350 kg. If blade is under tensioned the blade motor will not start. 10. Replace the blade cover and close wheels door. 11. -
Page 30: Blade Guide Adjustment
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. 1. -
Page 31: Carbide Replacement
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. -

Page 33: Angle Brake Adjustment
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. -
Page 34: Blade Tension Slide Adjustment
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: 1. Remove the head front cover. 2. Undo blade tension. 3. -
Page 35: 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. - Page 36 SECTION 4 - ELECTRICAL ELECTRICAL SCHEMATICS: SEE PDF ON ATTACHED CD...

Questions and answers
BLADE COLANT PUMP NOT TURNING ON PULLED MOTOR OUT NO POWER FEEDING PUMP
The Hyd-Mech S20P uses a pump and reservoir to circulate cutting fluid to the blade. If the blade coolant pump is not turning on, possible reasons include:
1. No Coolant Supplied – The machine does not come with coolant, so it must be added before operation.
2. Incorrect Coolant Mixture – Ensure the coolant is mixed correctly:
- Oil-based: 1:10 ratio (one part coolant to 10 parts water).
- Synthetic: As recommended by the manufacturer.
3. Electrical Connection Issues – Check for shipping damage to electrical conduits, cords, or hydraulic hoses.
4. Power Hook-Up – Ensure the machine is properly connected to the correct three-phase AC voltage.
5. Control System Issue – The pump may not activate if the machine is not set in the correct operational mode.
Verifying these factors should help identify and resolve the issue.
