HM126 Operator’s Manual 6. PLACING THE HEAD ON THE TRACK At this point, most of the sawmill head bolts should only be hand tight. They will be fully tightened when the head is on the track and has settled in to a true and square state. There are two methods in which the sawmill head can be lifted onto the track assembly: METHOD 1 If a tractor or forklift is available, the head can be lifted onto the track with a lifting strap or chain...
HM126 Operator’s Manual METHOD 2 At least two people are required for this step. Start by removing the two (2) carriage stops from one end of the track. The head can be walked over to the track until positioned behind it (Figure 1).
HM126 Operator’s Manual ROLLING THE SAWMILL HEAD ASSEMBLY Roll the sawmill head assembly along the full length of the track to ensure it moves freely. If it binds or is difficult to push it is likely the track is not square, straight, and/or level. Make the necessary adjustments to the track and roll the head assembly again.
HM126 Operator’s Manual RAISING & LOWERING THE SAWHEAD The lift mechanism is equipped with a self-locking, spring-loaded crank arm that prevents the head from lowering during cuts. When winding the head up or down, the operator pushes the handle towards the mill as the crank arm is turned. When the desired cut depth is reached, releasing the handle will lock the arm into one of the slots in the indexing plate.
HM126 Operator’s Manual LEVELLING THE SAWMILL HEAD ASSEMBLY Using a tape measure, measure the distance from the blade to the top of the log bunk on both the left and right side. The distance should be equal. If the measurements are not equal, adjust the lift cable ends under the lift mechanism sub-assembly to either raise or lower one side.
HM126 Operator’s Manual GREASING THREADS Add waterproof grease to the threads of the blade tension T-handle and to the mating bearing face prior to use. **Note: It is very important to take the tension off the blade by turning the T-handle in the counter-clockwise direction when the sawmill is not in use.
HM126 Operator’s Manual ENGINE OIL Refer to the engine manual before using your sawmill. Please note that the engine does not contain any gasoline or engine oil when it is shipped. Furthermore, the engine is equipped with an oil alert system, meaning that if the crankcase oil level is low or empty, the power is cut to the spark plug and it will not start.
Page 56
HM126 Operator’s Manual The engine comes with a brass oil drain extension to make oil changes easier. When removing the drain plug, use a wrench to hold the brass extension stationary while a second wrench loosens the plug. Failure to follow this procedure could damage the threads in the aluminum engine block and void the warranty.
HM126 Operator’s Manual DIRECTION OF CUT Always cut in the direction shown below. The log clamp is located to the right side of the log with the log supports on the left. Failure to cut in this direction can cause the log to come loose and possibly cause damage or injury.
HM126 Operator’s Manual SAWMILL SET-UP PROCEDURES DRIVE BELT TENSION Make sure the blade is under proper tension when setting the drive belt tension. This ensures the belt is fully seated into the pulley grooves when the deflection is checked. See section, BLADE TENSION, for more information.
Page 59
HM126 Operator’s Manual Once both bolts are loose, firmly push the belt tensioner towards the band wheel until the belt is tight (#1), then tighten the upper bolt in the curved slot in a clockwise direction using a 13 mm socket (#2).
HM126 Operator’s Manual BLADE TENSION Proper blade tension is achieved when the thrust bearing is flush with the outer face of the spring washer holder after turning the T-handle clockwise. Spring Washer Holder Flush Proper Tension Thrust Bearing No Tension If the spring washer holder is removed for maintenance (e.g.
HM126 Operator’s Manual BLADE TRACKING Never attempt to adjust the blade tracking with the engine running. As a safety precaution, remove the spark plug cap. Gloves and safety glasses should be worn when working with the blade as it is extremely sharp. Right Side of Sawmill Left Side of Sawmill The blade should run with the same tooth-to-front band wheel face distance on both the drive...
HM126 Operator’s Manual REDUCING THE BLADE TENSION Loosen the blade guide holder assembly bolt using a socket/wrench. The shaft should now be free to slide rearward and out of the way. Perform this step on both blade guide assemblies. This ensures the guide bearings will not influence the tracking of the blade whilst being adjusted.
HM126 Operator’s Manual ADJUSTING THE FOLLOWER SIDE TRACKING The follower side band wheel shaft is connected to the RapidChange blade system. Once the tracking is set, it maintains these settings even without a blade on the sawmill, allowing for quick and simple blade/belt changes.
Page 64
HM126 Operator’s Manual Turn the T-handle clockwise until proper blade tension is achieved. While wearing gloves, spin the band wheel by hand and observe how the blade tracking has changed. Measure the distance again and repeat the above step to further compensate if required. The ideal measurement is ⅜...
HM126 Operator’s Manual BLADE GUIDE ADJUSTMENT Never attempt to adjust the guide blocks or the guide bearing with the engine running. As a safety precaution, remove the spark plug cap. It is also advised to confirm that the blade is tracking properly before performing the steps below.

HM126 Operator’s Manual SAWMILL MAINTENANCE CHANGING THE BLADE Never attempt to change the blade with the engine running. As a safety precaution, remove the spark plug cap. Gloves and safety glasses must be worn when changing the blade. Follow these steps to remove an old/worn blade from the sawmill: 1.
Never attempt to replace the belts with the engine running. As a safety precaution, remove the spark plug cap. Gloves and safety glasses must be worn when replacing the belts. There are two V-belts on the sawmill: a BX80 cogged belt on the drive side and a Woodland Mills polyurethane belt on the follower side.
Page 69
HM126 Operator’s Manual Next, remove the tension from the drive belt by loosening the M8 hex bolt (#1) and the M16 hex bolt (#2) by approximately one (1) turn—do not remove the bolts. Once both bolts are loose, the belt tensioner will rotate counter-clockwise until the idler pulley comes to rest on the band wheel...
Page 70
HM126 Operator’s Manual The follower belt is changed by prying it off and installing a new one with the aid of slotted screw drivers. The blade can now be re-installed, band wheel housing doors closed, and proper blade tension set. **Note that blade tracking should not have changed after replacing the belts.
