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. -
Page 62: Engine Oil
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 63 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.

Page 65: Sawmill Set-Up Procedures
HM122 Operator’s Manual SAWMILL SET-UP PROCEDURES 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. -
Page 66: Drive Belt Tension
HM122 Operator’s Manual 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 67 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).
-
Page 68: Blade Tension
HM122 Operator’s Manual BLADE TENSION Woodland Mills sawmills use an ACME threaded rod for blade tensioning mounted within an assembled stack of Belleville washers for blade cushioning. This combined assembly allows for predictable and repeatable tensioning throughout all temperature ranges with minimal wear and maintenance. -
Page 69: Tensioning Methods
HM122 Operator’s Manual TENSIONING METHODS With the recommended tension range for milling in mind, the operator can decide how to tension the sawmill. Choose one of the three methods from below: 1. Torque Wrench Method: Use a torque wrench to tension the sawmill each time it is used. -

HM122 Operator’s Manual BELLEVILLE WASHER STACK If the spring washer holder is removed for maintenance (e.g. greasing or replacement), ensure the twenty-four (24) Belleville washers inside are oriented and installed as shown below. There are five (5) groups of four washers (4)—each containing two (2) opposing nested pairs —with... -
Page 71: Blade Tracking
HM122 Operator’s Manual BLADE TRACKING Blade tracking is the fine-tuning of the band wheel angles to “hold” the blade during cutting. This “hold” position maintains the blade’s location during most sawing conditions, with the guide bearings and blocks acting as occasional supports. A properly tracked sawmill will hold the band portion of the blade centred on the belts without any guides in contact with the blade. -
Page 72: Test Procedure
HM122 Operator’s Manual TEST PROCEDURE 1. Always wear safety gloves and eyewear. Never attempt to adjust the blade tracking with the engine running. Remove the spark plug cap as a safety precaution. 2. Loosen the blade guide assemblies, push them back as far as possible, and secure. -

Page 74: Drive-Side Adjustment
HM122 Operator’s Manual DRIVE-SIDE ADJUSTMENT 1. Back off the blade from full tension by three (3) full turns of the tension handle. **Ensure blade guides are still pushed back and clear of the blade.** 2. Loosen the jam nut on the upper bolt. -
Page 75: Tracking Run-In
HM122 Operator’s Manual TRACKING RUN-IN Once the band wheel angles have been tuned and the blade’s “hold” position is correct as per the test procedure: 1. Fully tension the blade to 25 ft•lb using a torque wrench—or—snug the tension handle to the thrust bearing and then rotate it a further three (3) full turns. -
Page 76: Blade Guide Adjustment
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 77 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...

Page 78: Sawmill Maintenance
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. -
Page 79: Replacing Belts
HM122 Operator’s Manual REPLACING BELTS 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 BX48 cogged belt on the follower side. - Page 80 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-...
- Page 81 HM122 Operator’s Manual The BX48 follower belt is replaced simply by pulling it off and installing a new one by hand. The belt fits loose enough on the band wheel to allow for this. There is no need to remove the band wheel from the shaft.
