Ariens Company recommends that you have ad

justments made by your local Ariens dealer. He has the

tools. and know-how to properly perform these

maintenance adjustments which may be required to

keep the Sno-Thro operating at peak efficiency. The

Sno-Thro is equipped with the finest quality engine ob

tainable. However, should servicing be required, it can

be obtained from an Ariens dealer or an authorized

engine manufacturer's service station. Should you

decide to make adjustments on your Sno-Thro yourself,

Ariens recommends that you call your dealer for the

answers to any questions that might arise in perform

ing this work.

SHEAR BOLT REPLACEMENT - FIGURE 12

Occasionally an object may enter the collector and jam

the rakes. When this occurs, the shear bolts securing

the rakes to the shaft will break and allow the rake to

turn freely on the shaft preventing damage to the gear

drive. When this happens, turn off the engine, remove

wire from spark plug, remove the broken shear bolt and

Replace with a new ARIENS shear bolt. Use of any other

type of shear bolt may result in severe damage to the

machine. USE ONLY ARIENS SHEAR BOLTS FOR

REPLACEMENT. Lubricate rakeshaft according to in

structions in "LUBRICATION".

RUNNERS AND SCRAPER BLADE - FIGURES 2 & 12

The runners on each side of the blower housing, and

the scraper blade, along the bottom of the housing, are

all adjustable to suit conditions. Raising or lowering the

runners controls the distance the scraper blade is held

above the surface being cleared. Runners are adjusted

by loosening the two nuts securing each runner. See

Figure 2. Move the runner to the desired position and

retighten the nuts. Be sure to adjust both runners to the

same height to keep blower housing level. Uneven run

ners make the machine difficult to steer and will result

in an uneven clearing job.

Adjustment of the runners is critical to good cleaning. If

the machine is to be used on a gravel surface lower the

runners so the blower will not pick up gravel. After the

remaining snow is packed down, the runners may be

raised for close scraping. On smooth concrete or

blacktopped surfaces, the runners may be raised so the

scraper blade rests on the surface and scrapes clean.

The runners may be removed from the blower housing

and re-installed in upside-down position to reduce con-

tact area and thus reduce tendency to ride up when

clearing hard-packed snow.

The scraper blade is adjustable so it may be lowered to

compensate for wear. See Figure 12 and page 12 il

lustration. Loosen locknuts securing scraper blade and

move it down to compensate for wear. Retighten

locknuts. If the blade is allowed to wear down too far

the blower housing may be damaged.

ATTACHMENT CLUTCH ADJUSTMENT - FIGURE 16

The Attachment Clutch is adjusted by connecting the

chain to the spring just below the attachment clutch

rod. Connect the spring to a chain link so the chain is

snug but so the attachment idler (Figure f) drops away

from the blower drive belt with the lever all the way up.

TRACTION CLUTCH ADJUSTMENT - FIGURE 3

A drive disc adjustment is provided to compensate for

wear on the friction wheel. If slippage occurs when the

traction clutch is engaged, perform the drive disc ad

justment. This adjustment is possible without removing

the bottom cover. "Lock in" the differential during this

procedure.

FIGURE 3

Adjust as follows: Place Speed Selector in First. Tip

machine forward on blower housing. Tighten the ad

justment nut while turning the wheels until the wheels

begin to drag. When wheels begin to drag, the clutch

lever should be engaged and released to realign clutch

linkage prior to adjustment. It may be necessary to

repeat this procedure until proper adjustment is obtain

ed. Turn nut back three turns. Wheels should then turn

easily.

CHUTE CRANK ADJUSTMENT - FIGURE 4

In the event the chute crank fails to rotate smoothly

loosen the nut securing the worm clevis to the bracket.

This hole In the bracket is slotted to permit adjustment.

Position the worm so it aligns with the teeth on

Discharge Chute and there is a little clearance between

worm and the gear teeth. Tighten the nut. Rotate the

discharge chute through its full travel to see that it

turns easlily. Readjust if required. Lubricate as describ

ed in "LUBRICATION" section. Tension on chute crank
