------ PERINGATAN! ------

Alat berat yang bergerak saat pemeriksaan rem servis dapat menyebabkan orang cedera.

Jika alat berat mulai bergerak selama pemeriksaan berlangsung, kurangi segera kecepatan engine dan pasang rem parkir.


  1. Pastikan tidak ada orang atau penghalang di sekitar area alat berat.

  1. Lakukan pengujian rem pada permukaan yang kering dan datar.

  1. Kencangkan sabuk pengaman.

    Lakukan tes berikut untuk menentukan apakah rem servis berfungsi. Uji ini tidak dimaksudkan untuk mengukur daya cengkeram rem maksimum. Kemampuan rem untuk menahan pada RPM engine tertentu tidak sama di antara alat berat. Variasi ini terjadi karena perbedaan setelan engine, efisiensi power train, dsb. Selain itu, kemampuan rem untuk menahan juga berbeda.

    Saat rem servis diaktifkan, catat RPM engine kapan alat berat mulai bergerak. Bandingkan RPM engine dengan RPM engine alat berat pada tes sebelumnya. Perbedaan kedua angka tersebut mengindikasikan bahwa sistem mengalami deteriorasi.

  1. Pindahkan tuas pemilih transmisi ke posisi maju TIGA.

  1. Naikkan kecepatan engine secara perlahan ke putaran IDLE TINGGI. Alat berat seharusnya tidak dapat bergerak.

  1. Kurangi kecepatan engine ke IDLE RENDAH dan pasang rem parkir. Turunkan semua attachment ke permukaan tanah. Tekan sedikit attachment. Hentikan engine.

Catatan: Anda masih dapat mengemudikan alat berat saat dalam kondisi direm pada kecepatan PERTAMA di gigi maju.


PERHATIAN

Jika alat berat bergerak saat pengetesan rem, hubungi dealerCaterpillar Anda. Mintalah dealer untuk memeriksa rem. Bila perlu, perbaiki rem sebelum kembali mengoperasikan alat berat.
