Section 5: Maintenance

WARNING

Before inspecting, cleaning or servicing the machine, shut off engine, wait for all moving parts to come to a complete stop, disconnect spark plug wire and move wire away from spark plug. Remove ignition key, if so equipped.

Failure to follow these instructions can result in serious personal injury or property damage.

IMPORTANT: Do not allow oil or grease to contact the pulleys, drive belt or reverse disc. This can cause the belt or disc to slip on the pulleys.

Lubricate the numbered areas in Figures

5-4 and 5-5, as follows:

1.Oil the wheel shaft between the wheel hubs and the transmission housing (A, Figure 5-4).

2.Oil all pivoting and connecting points on the Wheels/Tines/PTO Drive Lever and the Wheel Speed Lever (B, Figure 5-4).

3.Grease the face of the belt adjustment block (C, Figure 5-4).

4.Oil the Depth Regulator Lever, including the spring in the mounting bracket (D, Figure 5-4).

7.Grease left- and right-side engine mounting bars at the top, the middle, and bottom (G, Figure 5-4).

8.Grease the zerk grease fitting located on the pivot point at the end of the Wheel Speed Lever (H, Figure 5-4). If Wheel Speed Lever has a grease fitting on pivot assembly, apply 2-to-3 strokes of multi- purpose grease at beginning and end of tilling season.

9.Keep the PTO access area well-greased (I, Figure 5-5). If the Tines/PTO Clutch Lever becomes hard to move, squirt some oil into its access hole, and work it back and forth to disperse the oil.

Transmission Gear

Oil Maintenance

If tilling during very hot weather, the gear oil may heat up and expand inside the transmissions. To allow for this oil expansion, both the power unit transmis- sion and the tine attachment transmis- sions have oil relief vents (Figure 5-6).

Figure 5-6: Oil relief vent locations.

The vents allow small amounts of oil to seep out.

If a serious leak is discovered, please contact your authorized dealer or the Factory Technical Service Department for service advice.

Checking Gear Oil Levels

Every 30 hours of operation, check the gear oil level in both the power unit trans- mission and the tine attachment transmis- sion. Operating them while low on gear oil (even briefly) can cause serious damage to internal components.

Preparation

1.The transmissions must be cool, since hot gear oil expands and gives a false reading.

2.The power unit transmission and the tine attachment transmission must be connected when checking (or adding) gear oil.

Checking the Power Unit Oil Level

1.Move the tiller to level ground. Move the Depth Regulator up so the tines rest on the ground.

2.Use a 3/8" wrench to remove the oil level check plug on the left side of the

transmission housing (Figure 5-7).

The engines are designed for easy starting, even in cold conditions, so you won’t have to worry about fumbling with difficult pull cords when snowy weather strikes.

Another significant characteristic of these models is their 24-inch clearing width combined with a 21-inch intake height. This allows for efficient snow removal, enabling users to clear driveways and sidewalks with fewer passes. The heavy-duty auger system is engineered to cut through packed snow with ease, ensuring that even the toughest winter weather conditions don’t stand a chance.

Both the E682L and E682J feature a 180-degree adjustable chute that directs the snow where it needs to go. This puts control in the hands of the user, preventing snow from being thrown back onto the paths that have already been cleared. The quick-release chute deflector allows for easy height adjustments, giving users the flexibility to adapt to different snow conditions.

These models are also designed with user comfort in mind. The Troy-Bilt E682L and E682J come with heated hand grips, which make operating the snow thrower more pleasant during long periods in cold weather. The ergonomic handles provide a comfortable grip, and the adjustable handle height ensures that users of various sizes can operate the machine comfortably.

Additionally, both models feature large, rugged tires that provide enhanced traction on various surfaces, whether it’s icy pavement or a snow-covered driveway. This design consideration contributes to their overall stability and maneuverability, allowing users to navigate through challenging winter conditions with confidence.

In summary, the Troy-Bilt E682L and E682J snow throwers are powerful, user-friendly machines equipped with essential features that make snow removal efficient and manageable. With their reliable engines, robust clearing capabilities, adjustable chutes, and comfortable handling, these models are valuable tools for any homeowner looking to stay ahead of winter weather.
