MAIIMTEIMAIMCE
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 may be removed from the blower housing and re-installed in upside-down position to reduce con­tact 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.
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.
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
