Where do I call for technical support?
For answers to technical questions, call our Contact Centre in Woodstock, Ontario at (877) 276-7297.
What type of hydraulic oil is used on Hyd-Mech machines?
Texaco Rando HD46 or equivalent or machines built with Parker or Bosch Rexroth Power Packs use Shell Tellus 22 or equivalent hydraulic oil. The fill level is marked as a black line on the temperature / level gauge
What hydraulic oil filter is used on Hyd-Mech saws and how often should it be changed?
Hyd-Mech uses commercially available filters. When calling to order filters, please refer to the information listed on your current filter to obtain the proper dimensions as different sizes are used for our machines.
Filters should be changed after the first 50 hours of operation and then every 500 working hours after that.
What type of gearbox oil is used and what amount is required?
See owners manual for gearbox number.

What type of grease is used on all fittings?
Any good quality all purpose grease can be used. For the chrome shaft shuttle bushings LPS Therma-Plex Hi-Load bearing grease # 70414 is used.
My saw runs, but I have no hydraulic functions or any pressure showing on the system pressure gauge.
Between the hydraulic pump and motor there is a bell housing containing a three-piece coupling. Inspect the coupling to see if one of the flanges has loosened off and slid apart. If it is necessary to re-connect the coupling, use removable Loc-Tite on the set screws, or if the coupling is damaged, it will need to be replaced.
With new saw installations, if there is no pressure showing on the system pressure gauge, it is likely that the phase wiring is backwards. Reverse any two of the three phase wires supplying power to the saw.
Hydraulics will not stay running after the start button is released.
The out of stock limit switch on the shuttle vise may be tripped or damaged.
On Mitsubishi controlled saws, the blade shuts down after running just a few seconds.
There may be a problem with the blade speed proximity switch, which also functions as a blade breakage switch. The broken proximity switch option can be turned on / off through the parameters to enable the saw blade to remain running until the proximity switch can be replaced. Contact Hyd-Mech to obtain the correct password to enter the parameters.
On my inverter driven machine the blade shuts down and will not restart.
Disconnect the supply voltage to the saw for approximately five minutes. Turn the power back on and try to restart the saw blade. If the alarm or fault code persists, call the factory with the saw serial number, inverter model number and the fault code.
Are parts or upgrades available for older saws?
Parts are available for older saws and most Hyd-Mech models can be upgraded to current systems. Please contact Hyd-Mech or your local distributor for pricing and availability.
Can OES PLC controllers be upgraded to the Mitsubishi controllers used today?
No, due to design changes and electrical layout, this is not feasible or cost effective.
My chip auger has stopped turning on my saw.
The chip auger may be jammed with a thin piece of metal. If you are unable to locate or remove the obstruction, you need to reverse the auger rotation. Lower the head fully down, shut off the hydraulics, and reverse the two conveyor hoses at the hydraulic manifold. Start the hydraulics, raise the head, and switch the head to the down position and the chip conveyor will run in reverse dislodging the piece of metal. Then put the hoses back as they were initially.
What are the chip conveyor hose numbers?
H-Series Machines- Hose numbers are 44 & 44T
M-Series Machines- Hose numbers are 44C & 44T
