Setup
Unboxing and Initial Placement
The DeerRun treadmill comes pre-assembled. Carefully remove it from the packaging. Place the treadmill on a flat, stable surface. Ensure the power switch is in the OFF position before plugging it in.

The treadmill features a folding design for easy storage and setup.
Installing Handrails (if applicable)
If your model includes handrails for running mode, ensure they are securely locked into place. While the unit is largely pre-assembled, some models may require a simple setup of the handrails upon unboxing. Refer to the included quick start guide for specific instructions.
Power Connection
Locate the power input port at the front base of the treadmill. Connect the power cord securely to the treadmill and then to a grounded electrical outlet. Turn the main power switch to the ON position. The LED display will illuminate.

Operating Instructions
Powering On/Off
Locate the main power switch, usually at the front base of the treadmill. Flip the switch to the "ON" position to power on the unit. The LED display will illuminate. To power off, flip the switch back to "OFF".
Using the Remote Control
The treadmill is primarily controlled via the included remote control.
- Start/Pause: Press the play/pause button to begin or temporarily stop the treadmill.
- Speed Adjustment: Use the "+" button to increase speed and "-" button to decrease speed.
- Quick Speed Presets: Some models may have quick speed buttons (e.g., 3 mph, 6 mph) for instant speed changes.
Safety Key
For your safety, always attach the red safety key clip to your clothing before starting the treadmill. If you step off or fall, the safety key will detach, immediately stopping the treadmill.
Modes of Operation
- Walking Mode (Under Desk): With the handrail folded down, the treadmill operates in walking mode with a speed range of 0.6-3.8 mph. This is ideal for use under a standing desk.
- Running Mode: With the handrail raised and locked, the treadmill can reach speeds of 0.6-7.5 mph, suitable for jogging or power walking.
Smart APP Integration (PitPat)
Download the "PitPat" app to unlock additional features and track your progress. The app allows you to record exercise data, participate in training programs, events, and connect with other users.

The LED display tracks your workout metrics in real-time.
Maintenance
Lubrication
Regular lubrication of the running belt is crucial for smooth operation and longevity. Apply silicone lubricant underneath the belt as instructed in the user manual. A small bottle of lubricant is usually included with your purchase.
Belt Adjustment
If the treadmill belt feels too loose, causes jerky movement, or is not centered, it may need adjustment.
- Tightening: Set the machine to a low speed (e.g., 2.0 KPH). Use the provided tool (usually an Allen wrench) to adjust the screws on both rear covers clockwise until the belt runs smoothly.
- Centering: If the belt shifts to one side, adjust the corresponding screw to bring it back to the center.
