8 Bad Excavator Operating Habits That Kill Your Machine

Avoid These Mistakes — Extend Equipment Life

Have you ever cut corners on standard procedures to meet a deadline? Do you dismiss certain habits as "harmless"? Ensen Machinery draws on over a decade of equipment manufacturing and maintenance data to reveal these common but damaging practices — habits that quietly shorten your excavator's lifespan and erode its value.

Habit 1: High-Intensity Operation Right After Cold Start

Problem: Engine oil hasn't reached all lubrication points yet, and hydraulic oil temperature is too low. Full-load operation at this stage causes abnormal wear.

Solution: Ensen excavators are equipped with an intelligent preheating system — the dashboard clearly shows warm-up progress. Follow the principle of "low-speed no-load for 3–5 minutes, then gradually increase load" before putting the machine under heavy work.

Habit 2: Slamming on the Brakes During Rotation

Problem: Using inertia to brake hard during swing creates enormous impact on the swing motor and reducer, leading to early cracking of the ring gear and motor housing over time.

Solution: Ensen excavators feature buffer rotation control to absorb some impact, but the best practice is "early deceleration, gentle braking" — especially when the boom is fully extended.

Habit 3: Using the Bucket to "Compact" or "Hammer"

Problem: The bucket is not designed for vertical impact. Dropping it onto material or using it as a rammer causes micro-deformations in the stick and boom, and generates abnormal lateral forces on the hydraulic cylinder piston rods.

Note: Ensen reinforced work devices pass strict stress testing, but this kind of abuse is outside warranty coverage. Use proper tools — hydraulic rammers or breakers — for compaction and demolition tasks.

Habit 4: Raising the Boom While Traveling Long Distances

Problem: A raised boom raises the center of gravity, increasing tip-over risk and placing uneven, excessive load on the swing bearing — accelerating wear.

Safety rule: When traveling, keep the working device 30–40 cm above the ground and maintain a steady, low speed.

Habit 5: Continuing Operation with High Hydraulic Oil Temperature

Problem: Running with hydraulic oil above 95°C causes rapid oil oxidation, seal aging, and a sharp drop in pump efficiency.

Solution: Ensen machines feature dual temperature warnings (visual + audible). When the alarm sounds, stop immediately, let the machine rest, and check whether the radiator is blocked. The easy-open grille design on Ensen equipment makes cleaning straightforward.

Habit 6: Operating Horizontally or Turning on Slopes

Problem: This is the most common cause of track derailment and tensioning mechanism damage, and it carries a high rollover risk.

Correct approach: Keep the machine aligned with the slope — travel straight up or down whenever possible. If a turn is necessary, do it on flat ground. Ensen's adaptive chassis leveling adds stability on moderate slopes, but it does not replace proper operating technique.

Habit 7: Skipping Idle Cooling Before Shutdown

Problem: Shutting down immediately after heavy load causes sudden oil flow loss in the hot turbocharger, leading to carbon buildup and potential jamming. Sudden cooling also damages seals.

Correct procedure: After high-load operation, let the engine idle for 3–5 minutes before shutting down. Ensen's electronic control system automatically extends fan running time during this phase to aid cooling.

Habit 8: Skipping Daily Pre-Shift Inspections

Problem: Failing to catch loose bolts, leaks, or cracks early allows minor issues to escalate into major failures.

Ensen design feature: Key inspection points — hydraulic pipe joints, track tension indicators — use color-coded markings and tactile references so daily checks are quick, visual, and hard to miss.

Treat Your Machine Like a Partner

Your excavator is more than steel and hydraulics — it's your partner in building value. Every standardized operation is an investment in that partnership. Ensen Machinery builds durable equipment and supports you with user-friendly designs and smart reminders, but the real key to longevity is in your hands: develop good habits, and your machine will reward you with years of reliable service.

Start today — review your daily routine, eliminate the bad habits listed above, and watch your excavator perform better for longer.
