  • Page 6 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.

    Manual. Hyd-Mech Group cannot accept any liability for personal injury or property damage due to operator errors or non-compliance with the Safety and Operating Instructions contained in this Manual.
  • Page 9: Responsibilities Of The Owner

    Responsibilities of the owner Organization of work This Operation and Maintenance Manual must always be kept near the machine so that it is accessible to all concerned. The general, statutory and other legal regulations on accident prevention and environmental protection must also be observed, in addition to the Manual material.

  • Page 12 Residual Risks The machine is still not completely de-energized if an electrical cabinet door type switch is locked-out. The line side of the disconnect switch itself remains energized. Variable speed blade drives store dangerous voltage in their capacitors, and this requires time to dissipate.
  • Page 13: Section - 1 Installation

    SECTION - 1 INSTALLATION SAFETY CONSIDERATIONS  All safety precautions must be observed during installation, operation, or repair work on the VW-18 bandsaw ma- chine.  Inspect the machine thoroughly before power hook-up. Pay special attention to the electrical and hydraulic sys- tems to ensure no damage was caused in shipping.
  • Page 14: Lifting And Shipping

    LIFTING AND SHIPPING To lift a VW-18 bandsaw with a forklift, it must meet the following minimum requirements; Capacity of 2800 lb (1270 kg.) at 48”(122 cm) from the mast, as well as 6’ (183cm) long forks. The machine should be lifted from under the base, at either side as shown below. (Head should be at 90º position before...
  • Page 15: Hydraulic Oil

    HYDRAULIC OIL The VW-18 bandsaw is supplied with Texaco Rando HD46 oil. If it is necessary to change the oil to a different brand, empty the hydraulic tank and fill it approximately 1/3 full with the new brand of oil and operate the saw through several cycles with maximum cylinder extension.
  • Page 16: Earth Grounding Procedure

    BEFORE START-UP THE FOLLOWING TWO POINTS SHOULD BE CHECKED 1. Signs of damage that may have occurred during shipping to the electrical cables and the hydraulic hoses. 2. The hydraulic oil level is between the upper and lower levels on the gauge. As supplied, the machine is set to run on three phase voltage as indicated on the serial plate and voltage label.
  • Page 17: Section 2 - Operating Instructions

    START-UP The VW-18 control console has been designed to simplify the operation of the saw so that the operator has the ability to stop any function at any time, and to be able to control all the functions of the saw remotely.
  • Page 18: Control Console

    CONTROL CONSOLE The operator console has the ability to articulate, and be adjusted for height, to suit the preference of the operator. It is arrayed with a complete set of controls to operate both the hydraulic and electrical functions of the saw. All of the selec- tor switches have to be placed in their neutral center position for the hydraulics to start.
  • Page 19: Left Vise

    HYDRAULIC START BUTTON: 1. Starts the hydraulic pump motor. 2. Machine disconnect switch must be in “ON” position. 3. The Hydraulic Start button is illuminated whenever the hydraulic pump motor is powered. 4. The head selector switch and vise selector switches have to be in their center, neutral position for hydraulics to start.

  • Page 21: Cutting Parameters Chart

    BLADE SPEED DIAL: This switch controls the blade speed which can be adjusted between 65 and 385 SFPM. The blade speed corresponds to the setting of the dial in relation to the scale. CUTTING PARAMETERS CHART A full size PARAMETERS CHART is mounted on the front of the base. The chart contains five steps for the operator to fol- low in order to achieve optimum performance of the saw.
  • Page 22 STEP 2 - SET FEED FORCE LIMIT The Feed Force Valve was originally developed as a means to limit maximum feed force, to prevent crooked cuts, espe- cially in wide materials. While it is possible to set the Feed Force Limit low enough that a dull blade would just stall and rub against the work piece, this may result in sluggish feeding.
  • Page 23 STEP 4 - DETERMINE OPTIMUM BLADE SPEED, V (ft/min) (m/min) The relationship between optimum blade speed and effective material width for various materials is represented on the graph shown below The graph shows that as effective material width gets wider or as material gets harder, lower blade speeds are recom- mended.

  • Page 25 Feed Rate Calculation Feed Rate for Blade Pitches Other than Optimum Pitch If the saw is fitted with a blade coarser than optimum (e.g... 1.4/2.5 TPI) we can still use the graph, but we go to the 1.4/2.5 curve. As a result we find that the FEED RATE is decreased to 1.3 in/min (133mm/min) for this blade. If however, the machine is fitted with a finer than optimum blade (e.g.

    Guide arm position wheel Guide arm locking handle. Clockwise to lock, counter clockwise to unlock. Manual head swing GUIDE ARM POSITION In order to obtain maximum cutting performance from the blade, the guide arm should be positioned within 1/2” of the top of the material.
  • Page 28: Head Forward & Retract Limit Setting

    HEAD FORWARD & RETRACT LIMIT SETTING The Head Retract & Head Forward limit switches are activated by their own respective targets. Each target is factory set. If adjustment is necessary, either target can be loosened and repositioned. The Head Forward target is set to control the distance the blade will advance past the vertical plane of the fixed vise jaw. The target is located on a rail along the left side of the base, near the carriage linear way.
  • Page 29: Control Console Position

    CONTROL CONSOLE POSITION The control console can be adjusted for height and angular position to suit the operator comfort. It can also be positioned below the table line height for safer loading / unloading of large material, decreasing the likelihood of a collision with the console.

  • Page 33: Blade Tracking

    BLADE TRACKING Blade tracking should be set so that the blade overhangs the front of each of the wheels by 4.5mm to 5mm, measured from the tip of the teeth to the face of the wheel. Tracking is preset from the factory and normally should not need adjust- ment unless a wheel has been replaced.

    HYDRAULIC OIL: The VW-18 is shiopped from the factory with Texaco Rando HD 46 oil. If it is desirable to change brands, the hydraulic system should be drained and thoroughly flushed with the new oil. Recommmended replacement oils:...
  • Page 35: Lubrication

    See Section 8 Specifications LUBRICATION The VW-18 was designed with a goal to minimize the maintenance required so as to reduce downtime. Moving parts of the VW-18 will require priodic lubrication nonetheless, primarily application of a general-purpose grease to the moveable guide arm, vise ways, and the ilinear bearings.
