COLD WEATHER OPERATION/POINTER ADJUSTMENT

COLD WEATHER OPERATION

Block Heaters

In extreme cold weather, optional block heaters may be

used. Block heaters are installed directly onto the crankcase

and are operated by plugging into a 110VAC electrical outlet.

Be sure to use appropriate gauge wire when using extension

cords and abide by all safety rules when using electical

power, power cords, and extension cords. Do not use block

heaters when the temperatures are above 20

F (-6.67

C).

Draining the Water System

When low temperatures fall below 32

F (0

C):

1. If the saw is equipped with an optional water pump, open

the drain petcock on the pump and allow the pump to

drain. Turn the water pump switch on for a few seconds to

purge any water remaining inside the pump body.

2. Tilt the saw UP and BACK to allow water to drain.

3. Tilt the saw FORWARD to allow water to drain again.

4. If an air compressor is available, blow out the system

by applying compressed air to the water inlet.

POINTER ADJUSTMENT

1. Lower the front pointer assembly (Figure 22).

2. Using 10-12 ft. (3-3.7 meters) of stringline, divide the

length of the string in half and slide the string into one

of the slots or gullets on the backside of the blade (as

viewed standing in front of the pointer). See Figure 23,

item 2. Hold both ends of the string in one hand and

pull the string taut (Item 3). Move your hand from side

to side until both strings are touching both sides of the

blade.

CAUTION — Block Heaters

DO NOT leave optional block heaters plugged in for

extended periods when temperatures may rise above

F (-6.67

C). The oil could “cook” inside the crankcase

and damage to the engine could result.

If the water system is not drained when the saw is not

in use and temperatures fall below 32

F (0

C), damage

may occur to optional water pumps.

3. Adjust the pointer rod (Item 5), by loosening the lock

knob (Item 4). Move the pointer directly over the middle

of the two strings in your hand and tighten the pointer

setscrew to lock the pointer in position. Repeat this

process for the rear pointer.

4. To raise the front pointer assembly (Item 1), first pull

back and up on the pointer cable. Secure the pointer

assembly in the desired raised position by locking the

cable between the jaws of the cam cleat.
