Page 41
HM122 Operator’s Manual When a desired push handle orientation has been decided upon, attach the push handle to the side of the post using two (2) M10 X 70 mm bolts and lock nuts as shown below. Fully tighten these bolts. The push handle can be adjusted/rotated forwards or backwards to suit the ergonomics of the operator in either ground-mount or sawmill trailer configurations.
HM122 Operator’s Manual THROTTLE HANDLE AND CABLE Use the hardware listed below to assemble the throttle handle to the push handle and route the throttle cable to the engine. M4 X 12 mm Phillips Pan Head Screw Throttle Handle Assembly Throttle Cable Barrel Clamp The throttle handle comes loosely pre-assembled.
Page 43
HM122 Operator’s Manual With the throttle lever in the idle position (fully open), route the cable around the front-right carriage post. Pass the cable through the thimble in the auto-lube bracket and pull the unsheathed portion of the cable through the hole in the actuator tab, then to the engine. Next, route the unsheathed end of the cable through the hole in the barrel clamp, pull it tight while ensuring the throttle handle is still fully open, and then tighten the M4 Phillips pan head screw to secure it in place.

HM122 Operator’s Manual TIGHTEN CARRIAGE WHEEL BOLTS Tighten the four (4) M20 X 120 mm bolts that fasten the carriage wheels to the carriage side plates. HM122-MY2020: Rev A Page 22-Oct-2019...
HM122 Operator’s Manual 6. PLACING THE HEAD ON THE TRACK Before placing the head on the track, the carriage wheel spacing can be set to ensure they will fit properly on the rails. Check the wheel spacing to ensure that a distance of 26in [660 mm] is measured from outside to outside of the wheel grooves as shown below.
HM122 Operator’s Manual 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...
Page 48
HM122 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).
HM122 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.
HM122 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 must be equal. If the measurements are not equal, adjust the lift cable hook end to either raise or lower the right side until it matches the left.
HM122 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.
HM122 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 53
HM122 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.
HM122 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.
HM122 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 56
HM122 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).
HM122 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.
HM122 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...
HM122 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.
HM122 Operator’s Manual ADJUSTING THE FOLLOWER SIDE TRACKING The follower side band wheel shaft is connected to an auto-tracking 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 61
HM122 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...
HM122 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.
Page 63
HM122 Operator’s Manual Using a feeler gauge or thick piece of paper (.020 in / 0.5 mm), place it between the blade and both guide blocks and then tighten the set screws. .020 in [0.5 mm] gap .040 in [1 mm] gap HM122-MY2020: Rev A Page 22-Oct-2019...
HM122 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 BX71 cogged belt on the drive side and a Woodland Mills polyurethane belt on the follower side.
Page 66
HM122 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 housing.
Page 67
HM122 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.
