Maintenance blades
Blade sharpening and/or replacement
: It is recommended that only KEENAN-
trained and/or qualified maintenance personnel should perform this task.
Blades must be kept sharp, as blunt blades will increase power requirements. Sharpening
must be done without taking the temper from the blades (without overheating). Blades can
be sharpened many times, but when this is no longer practical, they must be replaced.
8.5 Maintenance for bale handler models
There is a grease nipple fitted at the pivot point of each bale handler tine on the auger chamber
side of the machine. The grease nipple is fitted to the head of each M24 tine bolt. The following
maintenance should be completed on a monthly basis:
1: Apply grease to each of the tine bolt grease points individually.
2: The M24 tine bolt locknuts should be checked for tightness. They should be tight
enough to prevent the tine from having any side movement but still allow it to fall under
its own weight when let drop.
3: The rubber buffer should also be checked for wear or signs of damage, which may affect its
shock absorption. The optimum tine-to-top-knife gap is
235 mm
±
10 mm
, but this may vary
depending on application and the design of the tine fitted. Please consult your local service
centre for settings

4: Check that the operation of the creel, both up and down, is smooth and unobstructed.
5: Check that the creel rubber is in place, is undamaged and is lowering and raising with
the creel.
Note:
The creel rubber is fitted to prevent material from sitting on the top knife of the machine,
additionally preventing a build-up of material from getting under the creel and damaging it as it is
lowered. To prevent damage to this rubber, do not drop material on it from a height when loading
material onto bale handler arms
Add or remove shims as required
